I can't really speak to XBox as it's not my field, but IE 6 was definitely not a clone of Netscape. I hate it with every fiber of my being, but Internet Explorer invented a bunch of stuff we take for granted every day -- the iframe tag is the first one that comes to mind, and they were also the first browser to adopt CSS, way back in IE3. People forget that for a hot second in 1995 Netscape started swinging its weight around as the dominant browser and introduced a bunch of half-baked ideas (the layer tag, for example). IE6 was a terrible browser, but it was the best browser at the time. The anti-competitive behaviour helped, and then of course they sat on their laurels for years, but the best browser won.
