>That assumes the individual’s right to speak is greater than the community’s right to shut them up, and is therefore biased in favour of the individual.

I completely disagree. The individual's right to speak is greater (at least in the US) than the government's right to shut them up.

However, other individuals (or a group of individuals, such as a corporation like F-Droid) have the same right to speak, as well as the right to control the speech on their private property.

There is an important distinction there. From a legal standpoint, the government are restricted from (except in very narrow circumstances) limiting an individual's speech.

However, private actors have no such restrictions on their private property.

a "community" of individuals can absolutely express their dislike/dissatisfaction with the speech of others by banning them from their private property.

It's only the government that's restricted from doing so.
