Freedom of speech is about censorship from the government. As much as Silicon Valley companies love to self aggrandize they are not the government and are under no obligation to allow their platforms to be used for furthering hate speech (or anything else.)
In fact I firmly believe sites like Reddit, Twitter and Facebook allowing racism and other horrible crap on their sites in the mid 2000s until recently is what helped make it more mainstream. In the web of the 1990s these idiots would have had to go to their own sites that nobody else goes to. Mainstream sites like Slashdot or whatnot didn’t tolerate it. For some reason after the dot com crash the new round of sites afterward have had some kind of delusion that they need to uphold free speech. And it’s nonsense.
