I like AGPL in theory, but in practice it never works like that. They are protected by a smoke screen — you don’t know if they are using something, how they are using it, or what they’ve built on it — and even if something did leak about their usage they are protected by money — the vast majority of FOSS projects won’t have the resources to pursue any kind of legal enforcement or reasonable remedy. In practice, they will use and build on A/GPL software while contributing nothing back in blatant violation of the spirit and intent of the license, because who is going to find out or enforce it?

They do call it "open source" in the docs though.

True, but I have no issue preventing commercial use. I view that as just as good if not better than traditional open source.
