Exactly. I have frequently pondered why Bob is (or was) doing this.
His behavior is even more inexplicable when you consider that early in the pandemic, he (along with his wife and colleagues) actually published a legitimate, good quality paper on the potential use of famotidine (an experimental antiviral) as a SARS-CoV-2 therapeutic.
COVID-19: Famotidine, Histamine, Mast Cells, and Mechanisms.
Much like the vile paid anti-vax grifting Q-Anon $hills on this forum, he's getting paid.
I really don't know. I do see that in December, 2022, he published a book that is available on Amazon.com. Certainly, he's receiving proceeds from sales of that book. (It's a conspiracy book with a forward by RFK, Jr. Amazon tells me that people who bought that book also bought books by Joseph Mercola, RFK Jr., Peter McCullough, and a selection of other antivax charlatans.)
I did an internet search and cannot find mention of Bob after Dec., 2022.
Maybe fame, maybe revenge for not getting the "proper" credit for the mRNA technology he claims to have invented, but with everything else eliminated, chances are there's some sort of quid pro quo that underlies the grift.
That is possible. I have seen someone else speculate that he might have felt slighted by what he perceives as lack of acknowledgement for his work in mRNA technology. He actually had abandoned that work and moved on to other things by the time I knew him.

He’s still posting at his substack account:
