What is the value of Twitter to publishers?

Twitter designated NPR as state-sponsored media -- putting them in the same category as Pravda and other government propaganda. NPR decided to leave the platform.

NPR claims they get less than 1 percent of their revenue from government sources. Does that mean participation in Twitter isn't even worth 1 percent of NPR's revenue? If so, that says a lot about the value of Twitter, and maybe publishers should re-evaluate their commitment to the platform.
