Everybody is starting a Substack! Or griping about Substack! Or both! The buzzy newsletter platform is home to all kinds of publications, including some that are basically music blogs. It has also become a favored destination for prominent writers who’ve either jumped ship or been forced out from more established media outlets, some of whom (such as Glenn Greenwald and Matt Taibbi) are very publicly warring with the modern journalistic establishment. Substack is even subsidizing some of these writers, a program the company is planning to aggressively expand after recently raising $65 million. This aspect of the business has been controversial. Some have criticized the lack of clarity about how much writers on the Substack Pro model are getting paid, while others have raised concerns about the large number of anti-trans writers the company has chosen to sponsor. People who love to get worked up over the media business cannot stop arguing about it.
