They appropriated WebKit pretty quickly. Yes, that was freely available, but good ol’ Microsoft was able to reverse engineer before, and if they can do it, Google can!
Does that mean the end of BLOATWARE?
I actually don't quite understand this one. As far as I am aware there are two issues that might be claimed with one being copyright infringement in the case of code theft and the other being patent infringement if a company runs afoul of a patented feature regardless of whether the code itself is original. Code theft could be either a case of downloading company property to personal devices or hacking it via a disassembler, which granted can be useful for trying to figure out the encoding of pesky digital camera raw formats. In the case of disassembly, which isn't exact, it could still be regarded as code theft even though the rewritten version would not necessarily match the original. Beyond that Objective-C was different in a lot of ways from either C++ or C, even though it's a strict superset of C. The typical methods and common data types are different. I'm curious how something could be code theft there yet not here.
