I can 100% understand how some people can conflate "deplatforming" with censorship (there is an argument to be made that they're the same thing), but this isn't calling for deplatforming.
It specifically states: deplatforming has been done, but what we actually really need is these 4 extra (non-censorship-related) things.
I'm curious to hear an explanation of how either of the following 4 things are censorship:
1. advertising transparency
2. selection algorithm transparency
3. algorithmic boosting of fact-checked sources
4. funding academic research into the impact of online platforms
"We need more than deplatforming"
"Changing these dangerous dynamics requires more than just the temporary silencing or permanent removal of bad actors from social media platforms."
Right from your link. Wake up.
