Save all the free speech shit for when the government is cracking down on people because it doesn't apply to companies of any kind silencing voices or types of rhetoric. Being deplatformed by big tech companies isn't a free speech issue, nor is various companies saying they won't do business with Republicans who pushed the election fraud stories, or companies saying we won't work with you if you hire Trump press secretaries. They're suffering from the consequences of what their governmental free speech rights allowed them to put out into the world.
it kind of is
at some point you have to evaluate what it actually means to have speech
"b-but private companies making their own private decisions" only goes so far until you're saying that for ALL types of speech, often even including what can be said in the real world
the refrain is "if you don't like that you got banned then make your own company where you're allowed to say what you want," but now payment processors and web hosts are private companies making their own private decisions to prevent your company from even getting off the ground
it doesn't matter what your policies are, it matters what they say your policies ought to be, or you're not going to be able to establish and maintain that private company
and this isn't about lamenting that republicans are getting their shit kicked in for being assholes, this is about the precedent it sets moving forward, which is that all that exists now is all that should ever exist wrt "speech" online
you have reddit, you have twitter, and any new forums are implicit attempts to circumvent the things they don't let you say, painting a massive target on your back
