The points you're using to substantiate your argument are not really in line with the facts. Many browsers broadly share a single implementation for huge chunks of the web. Examples off the top of my head include NSS, WebGL, LibPNG, LibJPEG, and WebM. And it's inaccurate to claim WebM is "licensed" from Google; that's no more true than claiming that NSS is "licensed" from Mozilla. Both are open source projects accepting third-party contributions. People can happily use the code as is, contribute to changing it, or simply fork it off. Finally, you seem to have missed the fact that Mozilla is already working on an experimentatl implementation of SPDY in Firefox: http://bitsup.blogspot.com/2011/09/spdy-what-i-like-about-you.html http://bitsup.blogspot.com/2011/09/spdy-what-i-like-about-yo...
