I wouuldn't join anything run by Zuckerberg. Don't forget, USA federal government agencies had staff full time working with Dorsey and Zuckerberg to restrict discussions and posts related to federal elections, the covid pandemic, and other matters. This is currently before for Senate committees and the courts. I recommend never doing anything which benefits those companies.
Twitter is the only one which exposed this stood against this showing that the governments have Zuck by the balls, but not Elon.
