Huh. Haven't experienced that myself, having used a Master MX for several years (now in use by my wife), a VX Revolution for a few years before that (now my son's backpack mouse), and a Master MX Vertical most recently. My son has gone through several other Logi mice as his primary mice, too, but they've died of either worn out switches or feet (he's an avid gamer).

Not trying to invalidate your experience -- I've see with my own eyes a similar thing happen with rubberized coatings on laptops & keyboard wrist rests (other's not my own).

Just putting it out there that it's by no means the universal experience.
