Free speech on centralized platforms is a pipe dream. Every company always has motivations to censor including legal, financial, personal, practical usability, etc.

Just because the ticket has finally come in for censorship that offends your own sensibilities, does not change the fact that this dynamic has existed for the past two decades. The pot has been slowly boiling, and you are now realizing it. Good - jump out!

The only way out of this is decentralized platforms running on Free software, period.
