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.
Even Microsoft has this published for the dotnet install tool:
curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin <additional install-script args>
Microsoft.. The only company I have ever heard mention CRIME and BREACH and invokes their specter in .Net to do awesome things like.. Not let you enable websocket compression in SignalR.
