> Really, the permissive licenses allow the code to show up in places that copyleft licenses would not allow it. There are a ton of open source projects used in Microsoft Windows or iOS thanks to their permissive licensing -- and neither Microsoft nor Apple are legally obliged to give anything back.

This whole sentence is backwards isn't it? A libre license does not restrict code from being used by Microsoft or Apple, it is those companies that restrict their developers from using libre licensed code. The license doesn't care who uses it. Apple used the GCC project as their primary compiler for many years, contributing objective-c to it.
