That kind of seems like the difference between top-down and bottom-up standards. MS added a weird extension to IE to support their proprietary webmail app, and... actually it was great so people wanted it pulled in to every browser as a standard. Many other features from Netscape's blink to IE's scrolling marquee died natural deaths. HTTP/2 was what? Something no one wanted, imposed by Google? Is that too strong? Is bottom-up maybe better in practice?
