We point out a particular bad actor in violation of their own policies, and they do nothing. We complain loudly about it in the news, and they vaguely commit to "fighting" the problems that were already against their AUP... but not any specific named bad actors. Automated systems are chucked at the wall, but the actual people people are angry about are exempted in the name of "free speech" until it costs the company business.
This cycle repeats until a politician gets a bug up their butt about it and passes a law mandating platforms have more censorious policies.
If you start a competing free-speech twitter competitor, you're effectively "twitter for InfoWars fans, QAnon and assorted holocaust deniers". Likewise, the headlines if Twitter themselves softened their line would hardly be about standing up for free speech ideals...
