MobiusArcher: After siting here thinking things over for a few minutes I have come to the conclusion that I probably spoke too soon. My first reaction was that they were exploiting the charity (and its recipients) to get more facebook followers. More followers mean more money for themselves. This angered me greatly. I suppose its not that simple though. I do still believe they are doing plenty of exploiting here. In the end though, this exploitation is not doing any harm. It is in fact doing much good. Its also not as though people don't know that they are signing up for advertisements when they like the page.
OnLive rents a huge booth at PAX every year (well, at least the last two, all they've been in business, iirc). It's not surprising since they work like crazy to get their brand out at PAX (Penny Arcade Expo) that they'd take up Child's Play as a charity (also started by Penny Arcade). Sure, will you get some ad from it? Yeah. Who cares? They're kicking in money for charity, hell, they were giving their systems away for free to anyone who'd sign up at PAX.
I don't like OnLive personally, as in, it's not a service that I want, however as a company I don't really think they're bad guys. They certainly seem eager to win folks over to their cause. And if you have a Facebook account, your info is for sale anyway, might as well get a buck sent to charity for it.
StingingVelvet: Damn OnLive are really pushing, I hear their name everyday now through ads or news posts. They think if they can nail this streaming shit early they will always have an advantage when other companies get into it. More power to them I guess, though I will never support streaming for games.
I think they're in the market too early, the infrastructure isn't there. Then again a lot of people think the Wii graphics look just fine, so maybe now is the time.
