There are speech police in the real world. Workplaces don’t allow you to use slurs or to harass your co-workers.

That “speech police” traces to the government in the form of labor laws & regulations in the remit of the EEOC, eg, Title 7 of Civil Rights Act, Age Discrimination in Employment Act, Americans with Disabilities Act. Employers didn’t conceive of such workplaces policies on their own to invite lawsuits & put targets on their backs.

These laws do not apply to social media as a communication platform. Offensive expression doesn’t deny equal access/opportunities to platform resources they are under any legal obligation to provide. Should we put much confidence in social media companies voluntarily assuming unnecessary obligations just because?

It never made sense.
