I don't have in mind some kind of Soviet-style authoritarian state that would censor things and whatnot. Was just commenting on the more general issue of whether people would create things if it had no effect on their salary; I think many people would. I certainly would; actually I probably do more things as side projects than as "real" projects as it is. The incentive is that technology is interesting, and people using and commenting on my stuff is rewarding. How to actually set that up in practice, I have less confidence in. My own politics tend towards more Scandinavian style social-welfare state, rather than communism, because it seems much clearer how to make it work in practice (market economy, but with high taxes, high level of public services, and a strong social safety net).

Even within a strongly capitalist system like the US, being motivated by things other than money actually used to be closer to the norm for a large number of professionals. The current situation where people change companies a lot, get large bonuses, and have widely differential pay, is a pretty recent phenomenon. At Bell Labs, everyone got fairly similar salaries, despite the fact that some people were much more successful in research than others. Of course, you had to be at a certain level of success to get there at all, but once you were there, you just got the normal Bell Labs salary, with raises tied to seniority, old-corporate-style. Yet many people there excelled anyway, despite the fact that they could've sat around pulling the exact same salary without putting in much effort. Why? Because they were motivated by things other than money, I would guess.
