Being entirely based on FOSS is the #1 overarching priority of the entire F-Droid project and always has been. The person who blatantly didn't even bother to check the organization they're talking to, and offered up unsolicited spam for a pointless service... is the one engaging in snobbery.
I didn't know FDroid used entirely FOSS services. Strong disagree that when offering up something free to help with a problem that's clearly being had one must first do a deep dive on the org. This conversation could be as simple as "hey we like FDroid and would happily help support it by providing our service for free to make sure this doesn't happen again", "No thanks, we only use FOSS'.
