What I want to know is, why does Rumble have to block Brazil?? China doesn't need to ask any centralized to block China - they block them in their national firewall. If Brazil considers Rumble a threat to the nation - just block their ips already. This is not rocket science for a centralized platform (even an "alt" one like Rumble).

You don't have to be a tech giant either. Uganda successfully implemented a paywall in front of all centralized social media sites - in order to collect a tax from users. The stated motive was to get a cut of the revenue enjoyed by these companies. But the move had tremendous social benefits as well as citizens dropped Facebook and explored more decentralized protocols.
