Oh, that's easy.  Statements make it more likely that program
committee members will more likely accept the paper because it's "real
world impact".

And if you're an academic, it's publish or perish, because due to the
gamification of tenure track committees.  Apparently in some countries
the pressure is so huge that academics have started submit fake/sham
papers:

   The startling rise in the publication of sham science papers has
   its roots in China, where young doctors and scientists seeking
   promotion were required to have published scientific papers. Shadow
   organisations – known as “paper mills” – began to supply fabricated
   work for publication in journals there.

   The practice has since spread to India, Iran, Russia, former Soviet
   Union states and eastern Europe, with paper mills supplying
   fabricated studies to more and more journals as increasing numbers
   of young scientists try to boost their careers by claiming false
   research experience. In some cases, journal editors have been
   bribed to accept articles, while paper mills have managed to
   establish their own agents as guest editors who then allow reams of
   falsified work to be published.

At least in this case it appears to be real syzkaller reports,
although if they were submitting sham papers to sham journals, they at
least wouldn't be wasting upstream kernel developers' time.  :-)

It would be *nice* if researchers at *least* checked to see if their
reports had already been discovered using an unmodified Syzkaller (for
example, by checking the upstream Syzbot web pages).  After all, if
the unmodified/upstream Syzkaller can find the problem, in addition to
wasting our time even more, it's *clearly* not a new/novel result.

P.S.  If you want to push back on this nonsense, Usenix program
committee chairs are very much looking for open source professionals
to participate on the program committees for Usenix ATC (Annual
Technical Conference) and FAST (File System and Storage Technologies)
conference.  It's a huge amount of work; easily 40-60 hours of work over
3-4 months.  But it does get you to see what academics are up to, and
it's a way to help point out bogus research, and to push back on
research groups using ancient kernels (typically whatever kernel was
current when the lead professor was a graduate student)....

If you're interested, I can put you in touch with some of those
Program Committee chairs when they are asking me to serve --- there's
more than enough opportunity to go around.  :-)
