You can still say whatever you want, you just can't compel others (including businesses) to assist you in conveying your speech. This is really basic stuff, it is surprising how difficult many otherwise smart people are finding it.
I can't even go out and speak in a public square, because it's illegal. Internet censorship by corporations is still censorship.
Private censorship is still censorship, particularly when the public square is privately owned.
