It’s interesting that you bring up wrongthink. Banning free speech would be something like out of 1984, but what we have is far more subtle and insidious. A system that shows you only what it wants you to see, while tricking you into thinking you’re seeing what you want to see.
Anyway, you can support free speech while hating this algorithm crap at the same time.
The system isn't tricking anyone, if an individual is not aware of how social media algorithms work that is due to willful ignorance (in the case of children that falls on the parents willful ignorance).
I do personally believe banning the algorithms begins to fall into the realm of free speech regulation. I can hate the algorithm crap without thinking the government should regulate the internet.
