Just like everyone else who owns that model, and to whom over 90% of
such devices are sold? What does this have to do with autocross?

All autocross below prepared level is done on street tires, by rule.
You can argue all you want about how sticky they are or aren't, but
they have DOT stamped on the side and they are legal street tires.
1999 (and other, don't know if they ever fixed them) Corvettes would
pull the bushings out of the front control arms and cause them to grind
against the front crossmember under heavy braking. They'll do this on
stock tires with perfectly legal street use. They'll certainly do it
on DOT autox compounds as well. But when GM denies coverage, they're
not "protecting themselves", they're taking advantage of a loophole to
avoid responsibility for a design flaw.
I think there's a clear distinction between that claim and someone who,
say, goes in with a spun crank bearing after running a raised rev
limiter.
