It's just acknowledging that on Twitter there's an implicit division been content producers and consumers, and that the content producers are getting close to leaving and taking their followers with them now that there are viable competitors. Paying them to keep producing content is hardly novel.

In contrast, most people are on Twitter to read tweets produced by a tiny minority of Twitter users. These users are directly analogous to YouTube content creators (and indeed, many YouTubers are also active with large numbers of followers on Twitter). It doesn't take great business acumen to see the parallel, all you have to do is look at the distribution of follower counts.
