Your right to free speech ends when it turns into terrorism, racism or a call for a coup.
There are some things that should be banned, such as the twitter accounts that promoted the attempt at a coup in Brazil in Jan 8 2023.
These are the accounts that the judge asked to be banned. After Twitter didn’t comply they started sending fines and eventually outright banning it.
Free speech doesn’t mean you can say literally anything. It means the government cannot punish you for your political views. But they can, and must punish racism and anti-democracy speech.
Also, it’s a misconception that a decentralized service cannot be banned. In fact it’s not hard at all
Only tech savvy people figure out how to go around this system. Roughly 80% ~ 90% of consumers will not realize what’s happening or won’t bother figuring out a solution.
Hell, even if only 10% of the consumers paid a slightly higher price the company still earns more by buying your data.
Statistics are on the side of the company. Buying consumer data is always the best strategy for them. The only thing that can limit abuse of privacy and consumer rights is government regulation.
