I would have to hard disagree. I think free speech is one of the most important issues we face today, it's worth any price IMO, including the ultimate price.
Free speech doesn't mean being able to say anything one wants on every platform one wants to say it on. There are real free speech issues out there but I don't see how this is one of them.
I see nothing good about some billionaire buying a communication medium millions of people use every day but I'm happy to be told why this is better than Twitter being a public company.
Having research without free speech is useless.
