Employees choose what you see every day you use most social media.
Anyone who has the power to deny you information absolutely has more power than those who can swamp out good information with bad. It's a subtle difference yes, but it's real.
I don't quite understand how the Ressa quote in the beginning of this thread justifies banning dissent for being too extreme. The algorithms are surely on YouTube and Facebook (and Ressa's!) side here, I'm sure they tried to downrank distrust-promoting content as much as they dared and had capabilities to, limited by e.g. local language capabilities and their users' active attempts to avoid automatic suppression - something everyone does these days.
It's not an argument for banning doctors from YouTube for having the wrong opinions on public health policy.
There is no free flow of information. Never was. YouTube and FB and Google saying "oh it's the algorithm" is complete BS. It always manipulated, boosting whoever they feel fit.
