Luke Dashjr, a prolific Bitcoin Core developer, has been sent to Twitter jail: he received a permanent suspension for proclaiming he'll respond with appropriate force if anyone tries to force vaccination on him or his family. To avoid confusion it's important to clarify he does not have an anti-vaccine stance, rather he took a wait for more data approach instead.

Bitcoin is the future of money, a technology that is as fundamental to humanity as speech itself. It is paramount for mankind to thrive. Luke spent over a decade working on this technology, therefore taking away his access to public communication channels is great disservice to society itself.
