I had a similar discussion with some people at a barber shop back when Pre-Elon Twitter banned Trump. They were complaining about free speech and I asked if they knew what it actually meant (in the US). When I explained that we are ONLY guaranteed free speech from the gov't, and that Twitter was a private business and could ban whoever they want, the same way this barber shop could tell someone not to ever come back everyone got real quiet like "oh shit I have to rethink my whole world view". I actually got thanked at another time by one employee for telling them how it actually works.
