Sorry to hear that, although maybe we will meet at nostriga?

The permissionless rebroadcasting is the point, that's how we get censorship resistance.

Blossom and NIP-96 are designed for public media, neither have the expectation that the media will be kept private.

I wouldn't be opposed to making my blossom-server implementation support NIP-96, however I don't think it would make sense to add it as a requirement to the protocol since supporting two event kinds would double the complexity
