I have noticed this, too. The hacker and creativity bashing started in open source projects, which were taken over by corporations. Now that a sufficient number of "open" source developers are in the pockets of said entities, mailing lists are censored, conference speakers are censored and dissidents are silenced.

HN is one of the rare places where free thinking is still allowed (probably thanks to pg), but the new ideology is spreading fast.

On the bright side, this may be a good time to found a startup.
