No, it's not to serve users. Users don't want broken webpages either. It's to make their own browser look faster at the expense of webpage authors. Because users will blame webpage authors for their webpage being broken. Would they know that they could have this same page unbroken with slightly worse performance, no one would choose the better performance. Sure, there's something to be said about webpage authors getting off their butts quicker, if their webpage is actually broken, rather than just not quite as fast as it could be, but the majority of webpages are not actively maintained. Chrome is simply breaking those. With only 8 months of a transitional period, there's no two sides to this argument. What they've done is unresponsible in every way.
