> Running arbitrary code on a distributed network of end user PCs It's a bit more complicated than that. I run gitlab and gitlab runners for a living, I can tell. First thing first, you'd have to register a runner with a specific project. So no "arbitrary code". Second thing, unless you can push a branch to the project main repository, no pipeline is ran. So for your own personal forks you'd either rely on gitlab.com-provided free minutes or you run your own runner (and tbh, it's fairly easy). Last thing: you should not think of regular end-users. Think of middle to advanced users, that have a home server or something like that (homelabbers?).
