Actually Windows and Ubuntu are not a good example because the end user can easily perform updates without the computer manufacturer having anything to say. I would upgrade my mom's Android 8 phone, but I cannot. It is not the fragmentation, it's who's in control of the updates.

Heh, after years of prodding, my mom finally gave up her Android 4.4 phone last month. Instagram stopped allowing her to sign in from it. It was replaced by a Pixel 3, which no longer allows her to easily set up her third-party ringtone app among a plethora of other annoyances and disappointments.

"This is why I never want to get new phones or computers" was muttered probably about 15 times in the two hours I was helping her salvage content from the older device.
