This is 100% on point. I was excited about Cashu at first, but quickly got ridiculed, unfollowed and muted for asking a few simple, honest questions about tradeoffs.

That amygdala response is usually telling in itself, certainly doesn't do them any favors. There is perhaps a place for ecash on bitcoin, would make a great solution for emerging countries nationstate soft currency production, but it's worth being candid on limitations.
I still think Cashu is interesting and has potential, I'd love to see some privacy solutions built using it. But just because a project got funded, that doesn't mean it should ignore valid criticism, or worse, act hostile towards honest feedback.
The inability for calle and contributors to have honest discussions about tradeoffs and possible alternatives makes then impossible to work with. I probably would have at least been somewhat curious to try it for a few niche use cases, but the cashu devs has convinced me otherwise. Apparently they openly mock me in their group chats according to calle. They are a bunch of children.
