I never said they don’t believe in PFS. Don’t misquote me. They said they don’t believe it is needed (in their setup). You can listen to their CTO saying it here too: Private messaging via Session w/ Kee Jefferys | Opt Out Podcast
They said it is good enough without it clearly. And I deeply disagree with this thought they kept sharing. I really wonder why they suddenly now think that it isn’t enough.
