Fact of life is everyone copies Apple. Apple doesn't copy and paste things. They'll think deeply before copying. And will modify things to fit their unique needs and situation.
Unfortunately, those who copy Apple switch off their brains and pursue the "looks" ALONE, ignore the "feel" and just mess everything up.
The next big culprit is Google's Android with their let's just hide everything - hamburger.
Microsoft, the final boss, attempted to beat Apple in design. The result was Metro UI - a beautiful, text heavy, flat, design (they changed the name too many times to keep track off.)
Microsoft turned off their brains as well. The result:
They hid every thing - scroll bars, status bars and title bars. Wasted valuable screen real estate - empty spaces everywhere. Created a much hated start-screen with scroll bars that moved horizontally instead of vertically. And to make matters worse, moved in the opposite direction of scroll wheel. (Perfect if navigating with a finger but very confusing if using the mouse. It clashed with 20 years of mouse knowledge)
That's why people hated Windows 8.
Both Apple and Google riffed off Metro design. Google calls theirs material design, don't know what Apple named theirs.
If this article was titled, Who Killed Ports, 3.5mm audio jack, repairability, screws, or upgradable ram? The answer would still be Apple.
Summary: Prioritizing form over function is cancerous.
