First of all I 100% wholeheartedly agree with the message of this post. However I have a minor quibble: > Chrome broke half of user websites, the ones that were relying on touch/scroll events being cancellable Either I badly misunderstood or the author is asserting that 50% of all websites rely on touch/scroll events being cancellable. That's inflated by at least 100x. Exaggeration is doing no favors here; the rest of the article is pretty rational despite it being clear that the author is pissed off, but this one sentence undermines it. --- Unrelatedly: > We really don't have more than anecdote (and our metrics) on the "support" side, and no precise way to quantify the breakage. I'd love to have a more quantifiable way to make these sorts of trade offs. (Emphasis mine.) Wow. So they're breaking backwards compatibility in a standardized web API with no plan for how to measure the fallout? That's not very nice.
