Chrome is the IE in that it’s all the web devs target or test and the browser that every enterprise just uses as the assumed target. Safari is the late-stage IE that doesn’t add any features or modern standards that its (supposed) competitors add. Although Apple seems to have different and more strategic reasons than MS did. Apple just hates the Web because they can’t effectively tollbooth it, whereas I think MS just didn’t care about investing in IE after 2001 or so.
