From within “the industry,” I’m not seeing a problem. I start a project, I release under the open source license of my choice, I accept contributions on my terms … it is, after all, my project. Join my authoritarian project, or don’t. Start your own if you like.

So people willing to contribute under this authoritarian structure will join up. Are they supportive of authoritarian regimes in general? Not necessarily.

Any kind of project needing large numbers of people to coordinate is likely to be hierarchical, likely even authoritarian.
