As far as I am aware, you're still allowed to talk about all of those things? Has someone been prosecuted for speaking about any of those things? Like, actual criminal charges pressed for specifically speaking about those things?

Freedom of speech is not freedom to demand a platform to speak in. You don't have a constitutional right to a soapbox, just one to not be prosecuted for speaking from a soapbox you found. And unless you own said soapbox, you're relying on the owner of the soapbox to continue to allow you to use it.
