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.
