Way back in 2021, I called out #Substack as a scam because it was masquerading as a service provider when it fact it was paying certain writers (often secretly) to create content for them.

Substack fired Sam Thielman after he edited Spencer Ackerman's farewell newsletter which criticized the company. Now the company is under fire for appearing to act out of spite.
