Earlier quoted context omitted.
If ReSharper was called "The Programmer's Refactoring Suite" or if Visual Studio were called "The Programmer's IDE" I would see your point. I'm not simply referring to the decision to target a particular platform. That's fine. There's nothing wrong with having a narrow focus. But please stop pretending it's anything but a narrow focus.
In what way does ReSharper or Visual Studio communicate Windows only?
That said, the "sharp" in "resharper" actually does hint at its Microsoft nature, as it's the same sharp in "csharp"
