I'd never let anything so trivial as having to install Origin keep me from playing a genuinely good game.
And as I have every reason to believe that Mass Effect 3 will be an absolutely spectacular game, made by one of my favourite developers, yes, EA can have all the personal information they want. I'll be far too busy having fun to care that some massive corporation, which will likely never have any reason to so much as learn my name, let alone use my personal information (of which they will not have any more than, say, Valve and Google) against me, knows a little more about me than it did before.
