Isn't that what they exactly did? They got all the PC gamers on fire, got Carmac, got bought by facebook. Now they're reaching for the moon, they became so big that people started hating, you can't avoid that.
Literally no one is hating them for getting big, everyone hates Facebook and doesn't want Oculus (which makes awesome technology) ruined by them.
I don't think people are upset because they "got big", but because they were acquired by a corporation that signals a core shift in their ideals. If they were bought by Valve, or even Microsoft, I don't think there'd be nearly as much backlash -- because it's not that they're BIG, it's that Valve and Microsoft would not be pushing for a different market with their product (not to say they wouldn't later).
