Warning: Wall of Text because it's curteous to reply (and I'd rather do it in one post than spam the forum with each one separately). Also, helps to switch mental gear from "work" to "things I should be doing right now." Erm. Somewhat, anyway.
I do hope people will get informed on the subject before it comes to bite the society, as a whole, in the ass.
If you think STASI was bad, imagine a private corporate entity with the technological capability beyond STASI's wildest dreams at their fingertips. Or, don't imagine, because that's already in place - consider what can be done with that, especially in the areas of sociology and politics. I am slowly coming to accept that the distopian books I grew up on ended up treated as "how-to" manuals by some.
Starkrun: I'm a little curious as to what is tracking because i run some heavy hitter add-ons and see nothing...
Any pull from Amazon network can (and according to back-room discussions is) used to grown their own mega-database. Amazon is very much trying to catch up to Google now that it turned out inconsequential details of people's lives (which most of the population is willing to share often without even being baited with some "freebie" service) is the hottest commodity around.
For that matter, I'm not even sure what is transferred to cloudfront.net when you pull the script from them. Your IP and the hosting website are pretty much a given, but it could also include "optimization" details such as browser fingerprints.
Might end up toying with this on the weekend when I have some spare time.
As Facebook proved, though, even a simple image from a third-party server can be used to generate a tremendous amount of data about an individual access point (which can rather easily be linked to a specific person). Hell, that's the major vehicle of Facebook's data-mining method (the prolific "f" buttons you see on most major web-sites actually do actively track you - whether you are a facebook user or not).
If you are genuinely curious, there is a metric ton of reading material on the intertubes related to just how little online privacy you are allowed nowadays. There's usually some serious article on the subject coming out pretty much every other day without even any related major event occurring. EFF, ACLU, and your favorite tech news site are probably the best places to start.
Unfortunately, while a lot of effort is focused on fighting government's access to private data outside of the established legal channels, people tend to ignore the growing corporate databases that the government can easily tap into (also, any restrictions on THAT would be totally against FREE MARKET©™!)
For lulz (and that's just the tip of the iceberg):
https://www.yahoo.com/news/belgium-officials-warn-against-using-190000193.html You hardly explained. Given how you yourself state that the actual code transmitted to a user machine is
you examined source code from a depository that may, or may not, be modified for Amazon's use. And I certainly do not believe for a moment that you did a full security audit of even the source code from github, much less the one transmited from cloudfront.net.
They still get your IP through the request, along with the website that you accessed. And only-Amazon-knows what else, since they can shape the pull request to include whatever browser fingerprints they want.
To... erm... "optimize" the experience. Yeah.
Amazon very much wants your data. They have no legal obligation to avoid gathering it when YOU ask for something from them. Do the math.
Somebody with factual knowledge of the subject... what are you doing in this thread? XD
Fenixp: I am one of those ... Ehm ... Rare professionals. And the rest of my office. ... Yeah, we're almost extinct. Anyway, I have checked where does it in any way connect to amazon or any other third party website and there's no such occurence, the code is fine.
"Security audit of the code in memory or GTFO." Basically.
Every bloody Defcon has challenges related to self-referencing coding or less complex methods of obfuscating code doing something else than it appears to do. It's not that difficult, a bunch of unis with security curriculum offers courses in writing these things for freshmen.
Though the above is more theoretical than actual accusation against Amazon. Things aren't so lax yet that they can pull this kind of a stunt without major public outcry (and there are, thankfully, still people around that would inform the public were that to take place). Doesn't mean they can't change things around when they so desire. Hey, stick an EULA on it, and nobody reads those anyway, right? Especially if you can blame somebody else (GOG in this case) for not informing the end user about the changes to data collection.
Most glaringly for somebody claiming to be a professional working with Java Script (or JScript, or whatever the flavor of it you prefer), you fail to even recognize that a simple invocation of the file transmits the IP address of the requesting machine, along with additional information that may further be expanded to accommodate online "fingerprints."
I mean, hello. Forest, trees.
Bottom line - I should not be required to run a third-party script (hello, potential attack vector) that is used for internal testing to be able to access my account hosting my purchases.
Trilarion: Is that true? I use ghostery and only see 4 trackers on GOG.com which I block.
It's true there are less on Steam (only 1) but I also block it, so the effective number for me is zero for both shops.
Facebook, Google, Twitter, Amazon are the ones that pretty much exist on all the pages of GOG.
Well, and Ghostery in your case - sorry, but those guys also monetize your information, though they claim it's only non-identifiable one, "cross my heart and die." A definition which, of course, does not include your IP address or browser fingerprinting since that's totally non-identifiable. Well, legally speaking, anyway. For real, just check their own Privacy Statement (conveniently linked below).

It's extremely discouraging to see, with the rare occurrence or two, even those treating this subject with the seriousness it deserves display a glaring lack of basic knowledge.
At least somebody was interested enough to perhaps learn more, though.
