It has plenty to do with free speech, if you don't grasp that censorship exists at a government, business, publication, and personal level for whatever reason, you need to go spend more time out in the world. That means getting out of the country you live in.
You seem to have a problem understanding the difference between private and public. And I'm sure you're going to go ah-ha, but reddit is private. True reddit is private, reddit also bills itself as a bastion of free speech, or did...at one point. Reddit also claimed they're not banning ideas, they also claimed they're only banning actions. Which is of course why they've banned people for ideas, and treading on their 'safe space' policy, which is of course a feels based policy.
And you go ask the mod of Neofag who was shadowbanned* for asking for the sub to be unbanned because they never harassed anyone. So yes, that was a ban because of 'reasons.' And subs like SRS and Gamerghazi are already trying to get subs banned because of feelings, and things they don't like. There's no threat to them, or other people...it's all things contrary to their feelings. In their world, hurt feelings are "what is reasonable to protect themselves from."
*Neofag was a circle-jerk sub.
