Viking's Choice moved from Substack (the newsletter service, not the cool programmer) to Buttondown.
Apparently, Substack likes to cultivate an image of being respectful to all people, but not at the cost of opportunities to dominate markets.
First the why: Doyle says they left Substack because they were upset that Substack was publishing — and in some cases offering money upfront to — authors they say are “people who actively hate trans people and women, argue ceaselessly against our civil rights, and in many cases, have a public history of directly, viciously abusing trans people and/or cis women in their industry.”
This is very similar to the Joe Rogan and Alex Jones thing on Spotify.
