...Perhaps because Apple themselves took more than a bit of inspiration from Dieter Rams radios, which inspired both the iPod, as well as the cheese grater Mac Pro.
Apple promotes itself as being a great innovator of industrial design, giving birth to their designs in a social vacuum. But the truth is much more complex, and Apple's narrative tends to undermine the true contributions and historical progress made by others.
A Dieter Rams radio (produced by Braun in 1958):
While your point about Apple's "innovator" propaganda is well taken, that radio is just a square plastic box! You can certainly argue their iPods looked like old portable transistor radios, but that's kind of a matter of form matching function. There were literally hundreds of plastic transistor radios. You might as well have put a picture of a real cheese grater.
Apple's been on the other end of copyright struggles, too. In the beginning, Apple got legal permission from Apple Records (started by the Beatles), who agreed not to bring legal action as long as Apple Inc. never went into the music business. lol About 25 years afterwards Apple started "iTunes". They had to make serious concessions to the aging Apple Records label.
I don't think Apple is particularly litigious in the present era of copyright law. The laws and the economic environment basically requires companies to actively "protect" their IP. And Apple's not desperate, like when Toys 'R Us started threatening lawsuits to any business with "
'R Us" in the name. At the time, my local hometown store Camera 'R Us changed their name in response. But that was when the toy store was in financial trouble and looking for money anyway they could.
And I'm not even sure what fruit-logo company you're talking about. Raspberry Pi still proudly displays raspberries. Even the Orange Pi: if they had legal trouble with Apple, they certainly resolved it.
Apple does plenty of underhanded and immoral things, but picking on them for navigating the awful international copyright systems that already exist... well that's comparing Apples to oranges!
