If you don't think it's that big of a deal to leak metadata through nostr DMs, consider that the widespread and illegal NSA program revealed by Snowden was "just" listening to metadata.
Not saying it's as bad, but definitely not harmless.

It'd simply better than the status quo for dms on social network platforms. Use Matrix/SimpleX for critical comms.
Yes and no, I'd say. The lack of any privacy guarantee with the centralized platforms is pretty terrible, but the leakage is at least constrained to internal employees or government subpoenas, as opposed to being fully public with kind 4.
Definitely agree though that other channels or throwaway keys should be used for anything sensitive though.
Here I am to rant about keet again, well maybe not. I still hold that nostr shouldn't be the end all be all, clients should use nostr for what its good for, and should use other protocols and tools as part of a seemless experience. I think nostr does a great job at networking, a handshake if you will, it shouldn't be where we put large amounts of data or some other action better facilitated by the host of open protocols we have. Having these features integrated into damus or amethyst would be unstoppable.
