I think it is changing tho. Once some has tried VarAC I think they realise it works a whole lot better. I just did a 34 min QSO from. Africa to USA. Don't think I even got JS8Call to do that as it took too long on overs. Maybe the reason is US is quiter on VarAC so I could actually get through...

Fantastic qso. It troubles me that vara is all closed source, but it seems like varac is at least partially open for developing on.
Since you are on nostr snd HF, I'll share that I am currently working on a nostr over ham client. Will be a server and client setup written in python. Long ways out, but working on it.
