You have the right to say whatever you want, everyone else has the right to not allow it on their property.
There is no first amendment right to compelled listening. We aren't remotely close to having that. There isn't even a strong argument having been made for that, there is nothing slithering through the courts that would change that.
This is what happens every time people "cancel" someone, everyone agrees not to listen to them.
The separate standard for platforms is that people are just observing that they can't cancel the platform, easily. Just because they too will lose their own sounding board, which is ironically still being tolerated by said platform. But that is their only option.
