Disclaimer: long-winded anecdote and opinions ahead!
Years back, my wife and I were in a bar in Bangkok, her sipping on a whiskey something-or-other, and me drinking my crillionth Beer Chang of the day. I had been vaguely aware of the soundtrack playing - it was a Thai band with a floaty female vocal playing acoustic rock of some stripe, but I couldn't place the tune. We talked, and admired the scene, and finally, there it was! - I was listening to a cover of the entirety of Appetite for Destruction, and it totally rocked!
Now, I am sure that, had I asked, I could have spent a dollar or two on a burned CD of that band's album, maybe at the bar, certainly at a vendor out on the street. Was the band profiteering of of GnR's artistic work? I dunno: sure, in one sense (they didn't write the songs), but not really, in another (not anymore than a cafe act taking tips on their cover of someone else's work; they weren't claiming the work as their own). Geffen likely has more of an issue with that Thai rock band than GnR ever would.
I suppose my point is that IP may be an important facet of our consumer society, but it's a nuanced and complicated thing. Blatant knock-offs lie on one end of that spectrum, 'borrowing' technology (whether its protected (Axis lock) or not (liner-lock)) is another. Think of all the different trade names for any particular steel recipe, for instance! M390 = 204P = 20CV... we know that the magic comes from Brand-X's ability to manipulate that steel to their particular advantage.
Recently, I have taken a job at a tech company that so viciously protects its IP that, well, I really can't say too much more about it... Point is, the best way to make a thing is to make that thing better than anyone else. Keep your trade secrets secret, let the imitators do their best, and, as long as you have the right formula (and a little luck), you'll come out on top (capitalism!).
I've spent another lifetime in the cycling industry, and in 2007 (if I remember right), watched Specialized (a top-tier brand known for aggressively pursuing IP infringements) literally sue the pants off of Mountain Cycle. Mountain Cycle - a Portland based company - was selling a new road bike named the Stumptown (a nickname for Portland), which Specialized claimed sounded too similar to Stumpjumper, a mountain bike that they had been marketing for many years. Legal fees, etc., put Mountain Cycle out of business. The two bikes couldn't have been more dissimilar to anyone paying attention.
Going back to another spectrum: on one end there are creative types - the ones who bring new ideas to the table, and on the other end are the thieves and liars and cheaters and counterfeiters. Somewhere in the middle are ones who realize their own limitations, and are OK with doing what they can with someone else's ideas, while never claiming those ideas as their own and giving credit where it is due.
