If advertised duty cycles aren't a thing, then every SSD, printer, and paper shredder is breaking the law.

I'm not aware of anything in magnusson moss prohibiting you from indicating a devices designed workload-- whether it's pages shredded per minute, pages printed a month, or TBW / DWPD. It is well known that flash has a limited lifespan and no court is going to rule that burning through those cell writes with a commercial workload somehow entitles you to coverage under an implied warranty.
