This isn’t authoritarian in the slightest. If you think having your voice heard instead of silenced is an example of authoritarianism, I’m afraid trying to explain anything would be a lost cause.
"I’m afraid trying to explain anything would be a lost cause" that's intellectually dishonest. Don't participate if you wont explain your position and won't address arguments.
As I said and you didn't address - this is a powers issue. Governments don't just get granted one singular law and nothing else. That kind of law gives them overall power to regulate. If a government can tell a private entity that they have to host user content they don't want - then they can do the opposite as well.
If your not familiar with powers issues then you have a lot of education infront of you.
