Others responding to my speech by exercising their own rights to free speech and free association as individuals does not violate my right to free speech. One can make an argument that corporations doing those things (e.g. your Play Store example) is sufficiently different in kind to individuals doing it -- and a lot of people would even agree with that argument! It does, however, run afoul of current first amendment jurisprudence.

Either way, this is categorically different from China's policies on e.g. Tibet, which is a centrally driven censorship decision whose goal is to suppress factual information.
