Some time in jail or having to fight a fine for refusing to implement features in the constitutionally protected free speech code they author? If that is what it takes.

I do not want to go to jail, but if that is the only way to get to an outcome where people have confidence they can not be forced to add unwanted code to open source projects, so be it. But that is a pointless thought experiment because it will never happen.

I do not think anyone would be stupid enough to jail a FOSS developer for not agreeing to compelled speech, and if they did, an army of lawyers would be lining up to take the case I expect, with the full support of the public. It would be an insane thing to attempt.

We must loudly push back on the chilling effects intended here. Our free speech to write or not write any code we want will not be compromised.
