It was a problem with their revenue stream, which was documentation website -> banner for lifetime payment.

All customers already had lifetime access and couldn't pay more. Plus noone was reading the docs on the webpage anymore.

Recurring subscriptions, ads in AI products (think Tailwind MCP server telling you about subscription features.) Those were just two things I pulled out of the hat in a minute.

I can understand recurring subscriptions and ads in MCP being a bright line that the team doesn't want to cross. You will probably say it's a bad business model to not make everything a recurring charge and packed full of ads.

I've experienced this in my own life - I ran my own business and I had to choose between doing a worse job and enshittifying the product to make more money, or doing a good job but risking bankruptcy. I choose bankruptcy, because I believed strongly in doing a good job and not enshittifying the product. I don't regret it.
