For this incentive to exist, the app needs to be such an obvious memory hog that users start identifying it as the source of the problem.
Even then, a lot is required for most businesses to prioritize this (presumably) temporary issue at the cost of things like: participation in the AI race, other features, bug fixes, new markets etc.
Heck, sometimes software is so inefficient that it costs developer and tester productivity but a fix is not prioritized for years.
