We may both be partially right, the main dev I interacted with has Tel Aviv on his GitHub (also 'Hanna' being around the project, but apparently that is a surname not a first name, and a mistaken extrapolation on my part)

The lack of professionalism or seriousness was mainly in a private email chain with Armin. He added a single comment to this issue after that chain which was the gist of a couple of his replies, less snarky. Either way, the interaction left me disappointed, not a founder who seems interested in listening or learning imo.
