why not? with signal you're trusting their centralized infrastructure that depends on secure enclaves and other dubious tech. with nostr dms could be going to your own relays that you control.
with nostr there will be multiple compatible implementations that keep everyone in check.
it doesn't matter if the infrastructure is centralized if the communication is end-to-end encrypted. The communication is unreadable for anyone who doesn't have the keys as long as the communication is encrypted client side.
You’re still trusting a single implementation. It could get compromised and noone would know. with a decentralized protocol this is much harder.
