I'm just curious, after reading about this sale to celebrate DRM free service, it got me thing. Does this sale have anything to do with the negative feedback from the xbox one's DRM which eventually led to Microsoft removing it from xbox.

you must be new here...

???

DRM free has always been one of GoG's tag lines.

There is no correlation, it is only accidental.

or am I misreading OP...

Not really, no.
DRM-Free has kinda been GOG's major differentiating feature. It's about time for summer (or winter down here) sales held by DD outlets, GOG's just getting ahead early.

People here said GOG usually do Summer Sale. and I think #NoDRM hashtag is just a marketing elements from GOG. I don't think there is any relation between GOG Summer Sale and XBox One recent DRM-related-issue update.

Marketing element or not, the #NoDRM campaign was a result of the horrible XboxOne press conference. I'm sure they went with that for the Summer sale because of what happened to Microsoft. It's a great way to drag in a new crowd that would before have been unaware of GOG, simply because of the popularity of the hashtag right now.

Ah. I see. I don't really follow E3 events. But doesn't this kind of sale should be planned before even Microsoft do XboxOne press conference ? but, yes, perhaps #NoDRM is used by GOG in a way you said.

That is why I said : marketing element. To market the GOG brand itself. As the core value of GOG is No DRM from the very beginning. Well, any Blue text person could explain to us more clearly about this matter.

The sale was already planned. The hashtag wasn't. GOG is just attempting to cash in on the current trend. \

Good for them, I say :)

The sale was planned WAY before the whole Xbox One policy changes. It's a coincidence that Microsoft responded to the extremely negative criticism and changed the system restrictions around the same time.

Also while on the subject of this, I thought the hashtag thing on twitter was the laziest form of consumer activism I've ever seen (whatever happened to just emailing the companies you're not happy with?), but it worked so I guess that's something.

At the very most, I could see the whole "summer of no DRM" theme being a response to the rather significant anti-DRM vibe amongst gamers right now, but there's no way the sale itself has anything to do with Microsoft and their shenanigans.
