Heh, was wondering when you'd post something like this - eh if they have it on principle to not bother with Ubisoft due to their DRM scheme (or just loathing the company like me), no need to compromise that just on Obsidian's behalf. And any sales they lose to this line of thought will be more than made up by the rest of the consumers that don't care or think Ubisoft are a great customer focused company.
Hardly throwing Obsidian under the bus, besides they have Kickstarter.
