Counties can imprison or kill you for speaking incorrectly.
Companies? Only have the power to cause me trouble when they are oligopolies, e.g. big tech right now. It can be quite severe trouble, even if it isn’t literal imprisonment.
A house? I am aware that poverty (and being a minor) forces some people to live with abusive persons who can give them a choice of silence or homelessness. That kind of evil doesn’t scale up to affect everyone (perhaps if it did we might try harder to fix it?)
If they deleted the apps already installed on your phone, then I'd agree.
4chan, being the obvious exception, since content can be created anonymously.
That right, and duty, does not exist on a private platform that you don’t own. You are limited by the TOS and license that you, like most, willfully skip over. A private, non-government platform can tell you to STFU and Get Out and they don’t even need a reason, because it’s their platform.
You can easily set up your own free speech platform, but nobody is required to listen. That’s the main attraction of social media, a more-or-less guaranteed audience. At least until someone tells you to GTFO if you’re not hosting.
Do you allow any form of speech in your house or is your house a platform that censors speech?
