@stevenroose good question, no idea. I only learned about the project the day I posted about it here. Let me know if you find out anything.
@jr
AFAIK (which isn't much) they're using OTR because some of the CoyIM devs were/are working on OTR4 and they don't intend to support OMEMO.
@jcbrand @stevenroose @strypey oh wow ok
@jr yeah, that's why I said OTR was an interesting choice. I'm curious to know why they didn't use OMEMO. Maybe dev on Coy started before OMEME was production ready and they haven't had time to implement it yet?
