Well IE may not be so good I agree, but this does not mean that GOogle has no blame. I have experiences first hand Gmail responding with CSS exceptions to an IE browser and not to Chrome/Firefox. To validate my suspicion I revisited the site using IE emulation mode emulating firefox and everything was fine. So TBH when MS got slapped with the massive EU antitrust fine years back because of IE, that is being done today from a User experience perspective undermining the experience on certain browsers. This is just one example I am nor pro Microsoft or Google I am sure they both do it in one way or another but the fact is this kind of practice exists on both sides.
