I would even consider it by design - management doesn't want apps to be deleted so easily. It's a subtle nudge for a user to accumulate apps, which slowly increase and eat up disk space.

The justification is that if no one deletes apps often, the button to do so should be hidden away, so users don't "accidentally" delete an app. And the designers are just a cog in the wheel - they listen to the objective given to them by management and do exactly that.

This is why you see great designs from apps that are written/made by a single person, or from a small team that cares. One such example is IDEs like Intellij - the UI/UX design is very much geared towards developers (by developers).
