Hewlett Packard Enterprise announced that starting on January 15, 2027, lifetime warranties on all Aruba networking equipment will change to "limited lifetime" (End of Sales + 5 years). This was done to “simplify and standardize our warranty experience" and seemingly will affect products already sold to customers. The networking equipment in question is not consumer grade but enterprise level that could cost tens of thousands of dollars a piece.
I have a very hard time seeing how retroactively changing the warranty on products already sold could possibly be legal.
