It doesn't matter if there's no warning when it hits 1%, it matters if the behavior of the device changes several years into the product's lifespan for the worse, and without any warning that it will change or has changed.

It's also a bit nefarious that the slowdown coincided with a new product launch, so side-by-side comparisons show that the new devices are much, much "faster" than the old ones (which were slowed down without any notification). It's borderline fraudulent.

Good thing we've got people like you standing up for the trillion dollar companies of the world, though. They really need your help.
