I get why there are people that don’t like how some installers do this, but this trope is really turning into the “but I don’t even own a TV” of OSS commentary.
Just use the Docker image if you don’t like it. Or get their appliance which actually supports ongoing development.
If the answer to cloud enshittification is “I know! I’ll use a different company’s solution instead of this open source project because I want to make an outdated stand against curl|bash” then I think the thought process is misguided.
