My problem with a lot of big tech compared to traditional companies is that they get to benefit from the economies of scale of software that affords them great profit margins and not deal with the consequences. For example, people constantly say that there's too much content for Facebook to moderate, etc. Then maybe this is a broken business model? Compare this to a mortgage servicer that is regulated to have sufficient customer support. Their budget to do this grows much more linearly while Facebook's budget for support, moderation etc grows far more logarithmically simply because they barely have any support.
I'm not suggesting Facebook should be policing content per se, but they should be required to handle incidents in a timely fashion whether it's removing illegal activity (or reversing a mistake thereof), helping victims escalate harassment to authorities, or whatever.
Yes, this costs a lot, but perhaps that should be the inherent cost of running such a platform.
