It works through onion messages, basically Tor... which as anyone who has tried using it with Lightning can attest is too flakey for real world payments... every hop adds latency and failure probability, it's a completely retarded design
Lightning is private, and Bolt12 doesn't make it any more private... blinded paths, randomized scids, already exist... Saying Bolt12 is more private is a lie by the shitcoiners trying to attack the Lightning spec with it
Bolt12 is a Blockstream psyop to make Lightning wallets work with Fedimints
