When I launched Dragon Commander, my firewall alerted me of an attempt of the application to connect to an IP which belongs to Larian. Neither the game itself nor the game description inform me of this aspect of the game's functionality - and I have definitely not been asked for approval. This means, without my firewall the connection would have been established and data transferred from my PC to Larian behind my back. This fits my understanding of spyware perfectly, and is probably illegal in many countries.
After I had blocked the connection, the game started normally, so my data, which are my property and not Larian's, are still protected from being transmitted to Larian.

Would Larian mind to comment?

Possibly. I don't play online, and I see no reason why Larian should track single-player usage without the user's approval. The minimum information they get if I don't block this outbound connection attempt, is my IP and date and time of launching the game. Not really extremely sensitive information, I agree, but it's still my decision to provide it or not - or it should be. And I have no idea what other data Larian could steal from my PC (I'm not saying they do it, only that they could).

Be this as it may - I have asked Larian for an explanation, and let's see if and how they reply.

By the way, here is the definition of "spyware" according to Wikipedia:
"Spyware is software that aims to gather information about a person or organization without their knowledge, that may send such information to another entity without the consumer's consent, or that asserts control over a device without the consumer's knowledge."
With the exception of the "asserts control ..." part, this is exactly what I have observed.

Thanks. I would like to confirm that following your advice works and doesn't alert my firewall.

But this doesn't change my view on unapproved outbound connections. It can't be such a huge effort to add a liitle query like "Do you want the Autoupdater to search for updates?" before trying to establish the connection to your server.
That said, I know that many people complain that GOG sometimes takes a few days before releasing updates. But you shouldn't make the assumption that everyone is like that. I have seen it a couple of times that GOG does QA indeed, and doesn't accept updates which create more problems than they solve (I'm not saying this applies to your updates). I myself am happy to wait if that increases the quality of the software.
