@0x4d6165 Hm, I mainly see it used to describe the kind of FOSS enthusiast who is unreasonably evangelist about it and - crucially - ignores individual circumstances in the process. AFAIK that's the root of the term - techbro behaviour, but applied to FOSS evangelism.
I would *hope* that that is still how it is used, but perhaps it has scope-creeped...
