Platforms like to be inclusive of perspectives. If they have to choose between taking ethical action or embracing unethical perspectives... guess what. They choose to remain inclusive of even the most atrocious perspectives.
It really is up to the people (gov? oh god.) to hold these platforms responsible. They (notably FB and twitter) have demonstrated, over and over again, that they will not hold themselves accountable. Ethics are beyond their purview.
What? You demand government(the USA) to punish the victim(Twitter) to solve a problem?
The problem is the government(of Soudi Arabia) asking for the information from Twitter office in Dubai. On refusal Soudi Arabia government can sure to use physical power over Twitter office conveniently located very close to Saudi Arabia.
It's like punishing a bank employee who had to hand over the money to the burglar at gun point. Also the it was the punisher(The USA) who gave a gun to the burglar(Saudi Arabia).
No one is talking about “punishment” but you. The concept here is building mechanisms of accountability (again, nothing to do with punishment).
Applying your example, the ideal is more like a social system stepping in and providing a means for the bank employee to safely not hand over cash mid-burglary.
