Trump apparently reads at something close to a 6th-grade level, going by what his staff have said about having to simplify his briefings to the level of Saturday morning cartoons. He's not a potential customer for any premium newsfeed services.

Musk is not an apparent functional illiterate like Trump, but he unfortunately has a long history of choosing poor information sources and reacting accordingly. (The "pedo guy" case comes to mind.) He cares less about accurate news than I do, that much is safe to say. So I doubt he takes advantage of whatever higher-quality sources might be available to him. Not when the latest missive from Catturd69 is free.
