If you care so much about the users as you say then you will release the code in a docker image so they can continue using your product.
their target audience does not know what a "docker" is, much less wants to lease a server for hosting
You can teach someone how to rent a vps and run a docker image with one 10-minute youtube video. Then they can use the drag and drop editor and run the bot themselves. If they don’t want to pay for hosting that’s too bad. A vps to run a bot will cost a couple bucks a month.
It's actually pretty hard to install Docker... Add Docker official GPG key... Install a bunch of crap...
