But every NYTimes tweet is, essentially, a free advertisement. It doesn't post a simple comment or opinion (its writers do, sometimes), but every post from the official New York Times account is a brief summary of, and link to, a story on its own platform (most of which are inaccessible to non-paying subscribers). Yes - this is also true of almost every other media platform that tweets - but that makes this an argument about advertising content, not "speech."
