Is it really necessary to make an accusation like this? Haya's
research seems very detailed and uncovers some vulnerabilities that
escaped many of us over the years. Haya's clearly aware of DNSSEC and
it's been called out as a mitigation in every one of the papers I've
read. You write as if Haya has an agenda to undermine DNSSEC, but all
I see is unbiased factual statements in the papers.
It's a complicated story to tell and it doesn't make for clear
straightforward advice; for the forseeable future deploying DNSSEC on
the auth side makes you more vulnerable, as there are still more
non-validating resolvers than there are validating ones. But then
complete deployment of DNSSEC on the resolver side would make
everything better again. It's hard to ethically advise someone that
they should stick their neck out for deferred benefit of everyone
