I agree. Those are the facts, for sure.

No argument.

Strongly agree. This explains AWS's economic motivation. It's not that they just care so much about democracy and rule of law, though a liberal (read: Democrat loyal) employee culture there is probably also a source of pressure pushing them toward the move. In this case the stars align: liberal employees want it, and they can have it because it aligns perfectly with AWS's economic incentives.
I think where we part ways is in thinking this is good for society. My problem with it is not that it violates any laws, but that it amounts to an incredible concentration of power in the realm of cultural production.
These corporations are societally expected to uphold a cultural respect for free speech and the rights granted in the First Amendment, but there is no legal basis to compel them to allow speech or activity they do not approve of.
Extrajudicial behavior such as terrorizing a legislature is harmful to these corporations’ profitable predictability. Operators would be in violation of their fiduciary duties to allow such a direct threat to their bottom line to continue, let alone grow.
In other words, money cares more about itself than anyone’s feelings.
