Sooo... Microsoft links people to Microsoft's browser. This counts as controversy? Shady behavior? Please.
My company is B2B and we stopped supporting IE6 at all around the time I started working here. We just suggest clients either upgrade or deal with it.
Sure, XP is an obsolete OS. Modernizing the whole stack is a much better solution than adding a modern browser to an obsolete OS.
He's saying that they'd get a more modern browser by going to something other than IE, given that their OS can't possibly support the latest version of IE. We know there's nothing you can do to be up-to-date forever.
Except install Chrome.
