Do you think the censors of social media realize what they're doing? I don't. If they did, they'd realize what they do can as easily be turned against them. They could find they're not only disrespected, they're considered criminals, and the public will demand they be punished for their actions.
Some might think that could never happen, but the past reveals censorship ends with tyranny, and the created ignorance always leads to terrible hardships for citizens. Those that condone, or practice, the censorship always become useful idiots. They either lick the feet of their masters, or accept their "reeducation" in the camps built to house those unwilling to accept their loss of liberty.
