Control comes in different flavors. Is the US government covertly and directly compelling corporations like they did during Snowden era? Probably less today if I were to guess, and certainly less than China.
I think today the threat is not government overreach but rather that the tech industry and government have so many shared interests and back-channels that coercion is no longer needed, and probably the big ones would throw hissy fits if so. Instead, I think it’s a mutual back-scratching operation. During covid, the infrastructure was laid out, with corporations running the information errands. I think both sides found that to be much more comfortable, and yes I do believe that became the prevailing MO afterwards.
Race riots? Palestine protests? Luigi support, and similar current uncomfortable issues transcending culture war daily jabs? ”Lightly suppressing” such speech has corp-govt incentive alignment, and frankly might be necessary to keep people in check given the growing inequalities and dissent. Any large uncontrolled social media operation is a risk, even without amplifying or suppressing anything inorganically and deliberately.
