Does it? In what way? Introversion mentions that the game requires a key to run, but if GOG has pre-activated the game with a generic key and
removed the phoning home requirement, it isn't contradictory.
The developer says there IS DRM in the game and it WILL STAY that way. GOG said the game was DRM FREE, then said "OK, problem fixed", then said "no, NOW it will be gone any day now".
Of course, we can go to some lengths interpreting these statements. "This can't be removed" means "we won't remove it" and "DRM free" can be read as "it may contain traces of DRM, but they should be harmless". For some reason they never clarify what it truly means, and of course it is on purpose.
Now, I could live with a pre-entered CD key. But can I really trust that that DRM won't bite me on the future? If I ever click on "multiplayer", will my single player ability be at risk?
I guess GOG would say "No! Of course not! We don't have DRM on the games we sell!" Introversion would say "That sort of thing only happens to pirates! Shame on you for asking. What is on your mind? You wouldn't steal a car now, would you?"
There's different reasons to 'phone home'.
And there is one reason to make it optional: respecting the user. OK, two if you count "avoid a lawsuit for breach of privacy".
I like to know what is being sent and why. I may even allow it. But I don't like to be left on the dark about it. It is MY data that is being sent.
For all I know, they could be using my machine to mine for bitcoins!
