Wow! See sibling discussion on their forum:

https://forum.cryptonote.org/viewtopic.php?f=5&t=220

We are not alone who are in hard doubt about Cryptonote creators' sincerity!

Also one can find from this new thread on their forum, that the new Cryptonote creators' group who started shit-fork-opportunity web site & this thread do STILL mention bytecoin as reference real-coin implementation, and they call new sources as official ones to fork purposes only (without built-in constants).

Also because new group did announce they to make reference 'educational' but real coin, other than Bytecoin or Monero, i.e. being Brand New real-world coin, the Cryptonote team apparently want to jump in a leaving train?..

Or I completely can not understand what happens

But I do not believe to Cryptonote team after all, and I like to believe to Monero team.
