IE6 is back, baby! All that’s left is deep integration with some proprietary Google “standard” (I’m thinking AMP) and it’ll be the early 2000s all over again.
I’m not saying we shouldn’t all be rooting for the other players today and keeping a close eye on Google, just saying there is no way for Google to do nearly as much to hold back the web as MS did back then, even if they wanted to.
