Free Software Should Not Censor

> [...] some free software project maintainers think it’s OK to impose their political / ideological stances on who can use their software, and for what purpose it can be used. They are violating the zeroth freedom [The freedom to run the program as you wish, for any purpose] to advance their political agendas

I genuinely don't understand the point this article is trying to make. For one, who (beyond the law) has the right to demand that free software developers do (or don't do) whatever they demand?

Second, on a more practical level, both of the examples cited[1][2] keep their code bases on GitHub. If anyone disagrees with the direction of travel taken by the developers of those software packages, then surely they are entirely free to fork the repository and start developing it in the direction they want to take it.
