EA is chasing a very different segment of the market than indie developers. Fancy graphics and gigantic projects that need to sell millions to break even. At that scale (and aiming at the lowest common denominator of consumers) maybe piracy is a big deal, but there are indie games that seem to do ok.

Their problem isn't piracy so much as getting noticed with a marketing budget orders of magnitude smaller than most AAA games'. And to be honest, I suspect EA just likes using piracy as a boogeyman to blame their problems on and to rationalize the Origin service.

I don't know that overall numbers on the PC industry would shed much light on the indie dev scene since they're still a small fraction, but I've played a lot of great games in the last few years. On mobile I basically stopped bothering, with Monument Valley being the one recent exception.
