It doesn't have user IDs... seems like an odd selling point... if you have good end to end encryption who cares if you have user IDs? I imagine you could do network analysis and so on to try an determine a network of people to deanonymize... but if you have encrypted chats, you have no context... unless guilt by association is enough.
On the other hand, a bigger problem than IDs would probably be IP addresses, etc. Random IDs per-conversation would also go a long way.
