The same could be argued about any claim regarding any piece of kit, from any manufacturer.
You'll be saying next that we shouldn't be doing PM at all!
Never presume - or assume - anything; after all, "Assume makes an Ass out of U and Me"!
My argument would go something like this:- how can anyone claim that something won't occur within five (or any other number) of years, unless that period has already passed, and it can be shown that the "event" didn't happen! Has the kit in question been around "in the community" for five years?
That's what PM is all about ...
preventing failures.
Lastly, and out of interest, does the thing carry a five-year warranty?
