What you're describing isn't a free speech concern. Free speech was always meant to be a protection from government limiting speech.
You can be trespassed from public property like a library but the bar is very high and simply saying something they don't like will not hold up in court.
Electric companies, social media companies, grocery stores, etc can do whatever they want with regards to limiting speech. The only issue would be if the government compelled those organizations to limit speech, see the Twitter files for an example of government overreach almost certainly violating free speech protections or finding just how far they can go before legal liability.
