CP Schnorr is emeritus professor from Frankfurt university. He is respected for his work in cryptography. He has, pun intended, nothing to prove but still works and furthers research.

Yes, claiming that "this breaks RSA" is bold, but this implementation shows that there is some advance in doing so in the paper.

Therefore signaling that this is a "scandal" via the postfix "gate" seems just inappropriate.

Apart from that kudos for the implementation to Ducas!

Calling it the "Schnorr attack" would imply that the outcome of it is still uncertain. And it also would sound way cooler ;)
