GOG.com has the DRM-free angle fairly well covered, so there wasn't a lot of room left there unless they wanted to compete. I think the pivot towards a charitable focus was a reasonable move, even if not exactly in line with their initial goals.
Funny that GOG.com does its first (I think) 100% charity run at this moment: http://www.gog.com/news/charity_promo_pick_3_games_donate_5_...
It'll be interesting to see how it all plays out, maybe they'll find their niche.
I've stopped buying things from them, even though I want to, because my bank freaks out every time, due to "the high levels of credit card fraud originating from Cyprus".
In any case, I'm sure GOG is set up this way to avoid taxes so it's probably worth it for them, even if it's a hassle for some subset of their users.
Humble Bundle accepts them already.
