Yeah it was just a question of time the next FUD and shill campaign will get started.
OP don't be so naive and believe everything you read somewhere!
Cobra has nothing to do with Blockstream or Core!!Not one bit!
Even Gregory Maxwell said the white paper is still relevant.And btcdrak as Core contributor also said that would be ridiculous.
However an updated version of what the Bitcoin network is today is a good idea imo.And this could be add as a second version beside the original white paper.
I mean the network has changed so much the last 7 years, so why not document and publish it.
