The most obvious explanation to me is that Udi messed up somehow and lost all of his coins a couple years ago. He then started hating #Bitcoin and eventually decided to sell his reputation to recoup some of his loses. He is trying to destroy Bitcoin as he doesn't want to see any of his old Bitcoiner friends become fantasticly wealthy while he has fun staying poor.

Udi and his grifter friends will fail, they can't change Bitcoin. They will eventually run oit off money thanks to Bitcoin on-chain fees and they will go away. Another example of Bitcoin working as it is designed.
