I never understood why Canonical's attempts to be "brave" (as Apple would call it) result in Canonical pulling out, while attempts by other companies like Apple don't.
For example, Canonical made a very brave decision to switch to Unity, and now they're having to move away from Unity, which hints that there were enough users against it, and they pushed Canonical into this position (along with Canonical trying to allocate resources better).
But Apple "killed skeuomorphism" and there were tons of people complaining "MY NOTES APP WHITE INSTEAD OF YELLOW EWWW" (especially my parents), yet today they're still getting more users and they have so many on recent versions of their OSes. I supported the removal of skeuomorphism, but seeing so many around me and on the internet complain, I thought Apple would be forced to put it back everywhere. Instead, people just moved on.
When Apple makes a "pro" laptop without any USB A ports, people laugh, but then buy it. When Ubuntu makes a phone, Ubuntu regrets it. Why?
