YouTube hardly mattered on mobile at the time we're talking about, iPhone 1 didn't even do 3G. Gmail isn't a monopoly and never has been. iPhone came out just a few years after Gmail did, whilst Microsoft had Outlook/Exchange in the enterprise which practically was a monopoly. The Windows team didn't really care about slick UI until long after Apple beat them on that. And the reason they scrapped CE and tried to do UWP is because the Windows API was long ago on its last legs but they hadn't been able to upgrade it properly. Whereas Apple had managed the evolution of nextstep much better, and Android was free / a clean slate design with proper sandboxing, and better consumer apps.
