Note that it's much shorter and less extreme than the letter to #Harvard.

There are probably many reasons why. Thinking out loud:
* Trump and Trumpists had a long-standing animosity against Harvard.
* Columbia's capitulation emboldened them to reach for more.
* Harvard receives more federal money than Columbia, giving Trump more leverage.
