Does unity want to support games where the vast majority uninstall it within a few minuites?
Seems like having less of those games on Unity might improve Unity's brand.

To make your case, I think it would be more relevant if Unity decided to charge game publishers extra for publishing games that were only installed for some short amount of time on a device before going uninstalled. That is not the case here.
Anyway, I see where your mind is at, but I think the conclusion you came to is not correct. I don't see what incentive Unity would have to keep low quality games off of their product, they actively would want them to succeed to hit the thresholds for monetization. And besides, everybody already knows to judge the tool based on its potential, rather than judge it based on some mediocre games that came out and flopped, because that happens with any engine.
It's often easy to guess which engine a game is made on, because they tend to share certain elements (UI, rendering techniques etc).
If your engine is associated with poor quality games, than high value games may decide to use a different engine.
