Erm awkward, if one is a corporation using VPN for firewall and effective spam elimination reasons. Perhaps the rich will be able to afford the fines? So - rules for thee, but our (very important) corporate can pay for having a VPN. LOL sowing division some more.

How dare u use a VPN, you porn-addicted terrorist!! Wot u hidin?

My theory is that human nature will continue to find ways to subvert the 'authorities' when the latter get too repressive, and there is a natural progression towards nothing left to lose, time to lose it in the streets - i.e., riots, more violence and eventually, bloody revolution. The 'authorities' then try to crack down even more, and fill up the jails and there is a civil-war death-spiral for the nation, as all the fightingest and loudest (e.g. normal construction workers and teachers) are locked up, or worse, killed.

Will the Brazilians use alternative Social Media? Maybe they adapt and will use WeChat, Tictoc, Discord or Telegram, Instagram or whatever. So in effect, taking out Twitter will just devolve to many competitors in that space. Problem categorically Not Solved. People will find a way to talk to each other. Some have huge followings and they will just take their audience elsewhere. The 'authorities' can only clamp down on social interaction so much, even if it comes down to strange low-tech activisim such as silently passing small stamp-sized slips of paper, hidden from surveillance cameras, with a dark-web-address or just a QR code on it. PErhaps people will get tattoos to be photographed for secret messages. The 'authorities' will then try and control that activity. Etc.
