The issue is that managerial class of America, both in private and public sector, are in bed with each other. The government cannot suppress free speech using the frontdoor, but these social media companies (Meta, Twitter) as well as Big Tech machinery (Google, Apple, Microsoft, Amazon) act as a proxy for supressing political speech through opaque algorithms and straight up censorship.
We, liberals, used to be exceptionally devoted to free speech. Just look up ACLU's cases from the 90's and prior. We were against the establishment. Against the managerial class crushing labor. Against the fucking 3 letter agencies.
Now, my own party wants to turn America into an authoritarian censorship dystopia. It's hard to stand by that.
