It always amuses me how one can shape another one's thoughts and find allusions where there aren't any. CryptoNote and Bytecoin team indeed worked together. It's Bytecoin devs that created the vast majority of the code based on the cryptography that was primarily ours by design. As BCN devs were interested in playing around with the coins itself, our courses departed. That is basically the whole story. CryptoNote never envisioned itself stick to community and ecosystem creation. We simply let others do it.

I've recently contacted Bytecoin team and there are some interesting updates, which they promise to roll out in a few weeks.
