That's about the lamest appeal to authority I've seen in my life.
Steve Jobs was more than a little petulant, and tended towards hyperbole. The fact of the matter is, despite all the histrionics and pouting, he regularly did the exact same thing he accused other companies of. If he saw something he liked, he took it and used it in his products. Sometimes he paid, sometimes he didn't.
Unless you're copying the code line by line, or directly lifting someone elses graphical assets, using someone else's idea isn't stealing. It's not exactly like you can just go in and take an idea. You have to do the work implementing it yourself, almost exactly like the originator had to do. In the process, you might end up doing something better than he did, and he in turn could end up taking your improvements to use in his own products.
That's the way it should work. Unfortunately, we've got this idea in our heads that software implementations are exactly like mechanical ones, despite the fact that there are only so many ways you can do things in software. If things were to pan out the way the "infringement is stealing" crowd hopes, that coded ideas can be locked down for 35 years through patents, it would end up being the death of innovation in the industry.
Wanna know why? I'll tell you.
Eventually, most everything you can do in software will be patented. There might be a couple of new ideas here and there, but chances are good you won't be able to implement them without infringing 1000 other software patents in the process. That means the geek programming out of his garage with a brilliant idea won't have the money or the means to give his brilliant idea to the world. The best he could hope for is to sell his idea to a big multibillion dollar corporation who may or may not use it.
In other words, the very situation that gave rise to Apple Computers, the company you know and love and defend to the death, would be an impossibility if what you wanted were to come to pass. Instead, Apple computers would've had a brilliant idea they'd have to sell to IBM, because they didn't have the $400,000 minimum to license the thousands of patents necessary to create their first PC.
Software patents protect old ideas at the expense of new ones. Since a software patent is basically a patent on a concept, they're incredibly difficult to work around. Whoever gets to the patent office first basically owns the concept for 35 year. No one else can do anything with it without forking over a ton of cash.
Innovation dies.
