Microsoft doesn't Sherlock developers, it IEs them. Remember Netscape? Remember how Microsoft murdered Netscape and the web for a decade with their subpar but built-in recompile of Mosaic? Antitrust lawsuits? Any of that familiar, Jeff? Apple devs are well aware of the risks and choose to develop for the best and most profitable platform regardless. If Apple wants to build a shiny new road through our shops, we move over a bit and try again. Or you can develop for a second- or third-rate platform like Windows or Android or the web, but they're technically, aesthetically, and financially inferior, so few Apple-quality devs will.
