Well, read the top comment in this dicussion: They're not saying "if FB wants to kick arbitrary people including me I'm fine with that", they use "bigots" and "anti-vaxxers" as examples. Another important element is a constant refrain of "but platforms with no restrictions end up as a cesspool".
> We can see what definition is
"seeing the definition" just means seeing some flowery language which may or may not be the full truth when it comes to individual cases. If people don't pay attention to the fact that they don't actually know, and don't seem to care, who exactly is booted off these platforms and why, exactly and on a case by case basis, and just take the word of platforms like FB or Twitter for it, they're in for a rude awakening when they end up on the wrong end of it themselves.
The amazing achievement of not being a racist or an anti-vaxxer doesn't make up for the failure to clearly speak out against the hypocrisy of a company that on the hand hand fights democracies that want to protect citizens against tracking [0], to mention just one color in the spectrum of shit they're up to, while on the other hand bragging about how they're not evil. Facebook can do what they want, people and use their "services" all they want, and roll their eyes about "outrage over FB" all they want, but then they also need to own it.
