If you have a connection to California, you can be sued in their courts. I don't know whether providing (not selling, that certainly counts) an OS to California residents from outside California counts as a connection, that's something you need to review with your legal team. One thing is certain though: you need legal counsel to do OS dev; the Terry Davis era has come to a close.

Then let Californians do their dirty work. They have no place in the broader open-source community or in the rest of the world. Nobody should care about them, except now about caring about blocking them.

The owner of the computer should decide what the computer does.

California is a soon failed bankrupted US state, and no one outside its borders cares what's going on there. Companies are leaving, people are leaving. Let them sink to the ocean with their idiotic laws.
