Social media policy in the USA [closed]

As far as I observed, the US social media platforms are very sensitive to news related to Israel and India. Many contents that criticize Israel or India are deleted, or the users are banned.

Is this due to

1. those two countries' close relations and influence on the US government, or
2. is it because of the US law that governs social media and free speech, or
3. is it because of those two countries' markets, or
4. is it because all of the above
