The list is pretty short though for 8 months. ossfuzz has found a lot more even with the fuzzers often not covering a lot of the code base.
Manually paying people to write fuzzers by hand would yield a lot more and be less expensive than data centers and burning money, but who wants to pay people in 2026?
I can't speak to what exactly this team is doing but I haven't seen any evidence that with-robot finds less bugs than without-robot. I do have some experience in this area.
Bugs are not equivalently findable and different techniques surface different bugs. The direct comparison you're trying to draw here doesn't hold.
