If we have to use crypto (which I don’t really see a reason for to be perfectly honest), then I’d much rather seean privacy coin like Monero being used.

I am split here. I dont expect anyone to know the manages by heart, but at least doing a quick search should be possible. If that obviously wasn’t done I’m fine with referring people to the friendly manual.

RTFM nice(1)

I really don’t see a reason to write more just to summarise what has already been written. Is that toxic though? I don’t think so. If someone then says that they don’t understand what that reference means, I’ll gladly explain how manpages work and how to search for info. Teach a man to fish and stuff.

You might want to take a look at cage which has been designed for that.

That still requires some level of graphical session though

Not sure reality agrees here. Unless the project is huge, it will most likely not see any money. With copy-left code they are at least required to share their improvements and contribute that way. (I am aware of the no-gpl policies of many companies)

What’s probably a better Model are Nextcloud’s “SupportaaS”, Sourcehut’s consultancy, or mailcow’s SaaS. (I also see SaaS critically, but if it’s Libre I’m okay with it)
