Would he have gotten so far in politics without Twitter? Trump’s style of direct communication is very powerful for maintaining the attention of a passionate base which is the source of his political power.
Neither Twitter the company nor society at large is obligated to play into the game where a candidate figures pit how to make a non-traditional platform work for him and then expects help from others when it no longer works for him.
You can't live by the sword and then passionately advocate pacifism when a sword is raised against you.
