Apple’s business model is built on patents, not technology or ‘innovation’. Patent litigation is a growth industry. Do some reading on the subject, look behind the curtain on the right!
Most knife makers do rip each other off. The contemporary PC term used is "inspired". Most knife makers are infringing upon several patents. Just about everything is covered by patents, millions upon millions of them, many of them are BS. It's a guarantee that most of the items, or aspects of that item, in your house are patented and most of them are infringing upon several patents. EVERYONE making EVERYTHING is breaking patent law, end of story.

My IP attorney sister disagrees with you. I will take her 15 years of experience in the field over your laymen. The moral warrior thinks in terms of black & white until it doesn’t support their narrative, because theft is theft, right? Just because you don't understand something, doesn't mean it's false. To repeat what I said above, everyone making everything is breaking patent/IP law.
