This is new territory. This is actual censorship. Protests actions not otherwise illegal should be allowed on social media, in compliance with their TOS. This message from the administration is very close to a government official advocating for a third party to remove your free usage of a platform for allowed usage in ways the government may also disagree with. I expect the courts to frown on this for the same reasons that the courts decided against Trump banning people from his Twitter account which he uses for official government business.

I leave you with a poem.

The Cloths of Heaven

Had I the heaven's embroidered cloths,

Enwrought with golden and silver light,

The blue and the dim and the dark cloths

Of night and light and the half-light;

I would spread the cloths under your feet:

But I, being poor, have only my dreams;

I have spread my dreams under your feet;

Tread softly because you tread on my dreams.

W. B. Yeats

Original title was too long. It was:

Trump administration tells Facebook, Twitter to take action against calls to topple statues, commit 'violent’ acts
