But this change breaks functionality for some people, without correspondingly improving anything for others. So what's the point?

In my experience, software that is designed to work only for the most average user ends up feeling terrible for most everybody, because most people deviate from the average in one way or another, at one time or another.

It feels especially bad when the software makes assumptions about what the user wants, to the point of including a button that doesn't always do the same thing when pressed, and which doesn't even tell the user it doesn't always do the same thing when pressed.

Just look at all the complaints Microsoft gets for the way Windows constantly reverts or ignores user settings.

Or the way it feels to google a very specific set of search terms, only to receive back 20 completely irrelevant listicles that answer a statistically more likely question you didn't ask.
