FWIW, I never really saw it that way... my perception was that it was more of an "anti BIG business" and "anti proprietary / locked-down / walled garden ecosystem" sentiment. But that's not the same as business per-se. Lots of hackers started businesses and even rms says that selling software for money is fine, so long as user freedom is preserved.
That said, you have a fair point about the startup/hacker "thing" being a little more modern. Then again, 1994 was a pretty long time ago now. So I guess one could argue the point about whether that should be accepted as part of the hacker ethos or not at this point.
