Big Tech Censorship
This is where you may start to hate me already.
Is banning a person from posting or blocking an entire site or app the beginning of taking away our civil rights? Terms of Service are legally binding agreements.
Web Browsers can block whatever content they want. It's not censorship. It's called having rules. For instance, see Google's Terms of Service (legally binding) and scroll down to the subheading, "Respect". Most specifically...
"- don't abuse or harm others or yourself (or threaten or encourage such abuse or harm) -- for example, by misleading, defrauding, defaming, bullying, harassing, or stalking others"
This exact wording was in there as of version dated March 31, 2020. The last time their TOS was updated was October 25, 2017. At that time they simply stated, "We may add or remove functionalities or features, and we may suspend or stop a Service altogether."
In summary, be respectful, reasonable, nice, non-bullying, and behave with at least a modicum of decorum online and in person. I don't think that's too much to ask.
