At least one of the devs is an arrogant, condescending prick. Remember Nick the Computer Guy from SNL? He's like 3 times worse than that. I've experienced it first hand - as in his second reply to me was to blame me: "you're doing it wrong". He's exactly like some people I worked with 30 years ago. Smh.
There's far more than that, though. In general, the Graphene team says everyone else is wrong. Classic idealist attitude.
I run DivestOS now because of that interaction, I will never use Graphene. That dev can go fuck himself with a pineapple - had enough of his kind of childishness decades ago.
Having had a disagreement with Miguel De Icaza that boiled down to him saying "Well I have these books on my shelf so I'm right" (narrator: he wasn't right, it was hilarious later).
