Earlier quoted context omitted.
If you've used Xcode before, you'll recognize things they copied that are not the norm in other IDEs. The object library, IB screen, the layout buttons on the toolbar (the entire toolbar, really). Sure, it's just an IDE, but heck if it doesn't look strikingly similar to Xcode. edit: cmelbye in this thread has a good comparison: http://news.ycombinator.com/item?id=4378379
Other than the placement (but not iconography: those come straight from the 1980's VCR) of the Start/Stop buttons, I'm actually not quite sure that I see much. Can you elaborate? What's an "IB screen" (if it's the visual layout thing, I gotta say you're off by about 15 years trying to attribute that to Apple). But fair enough: let's say they cloned it. Now what? What corrective action should be taken? What if Eclipse…
But I'll bite: I do not think cloning a UI is fine. I think drawing inspiration from a UI is fine, because indeed, any new thing stands on the shoulders of what came before it. But actually cloning a UI (your words, cited) is making a clone, a copy, whose result is certainly not evolution or innovation. You're making a facsimile, doing no real creative work (or innovative work) to cut corners.
To me, this is less about it being Samsung and Apple, but about cutting corners in a blatant way. It's dumb, it's misguided, and these guys should know better. Just as you shouldn't ever say that cloning a UI is fine.
