        Happy, of course! We've been waiting for this day since @randomdross left Microsoft. Without him, it became useless.

        Also, Microsoft deserves a lot of credit for being the first to remove the XSS filter. @googlechrome should do the same next for XSSAuditor.

        Just to be clear, we are happy about the removal because these filters rewrite markup, and can be tricked, etc, right?

        Perf cost, false positives, false negatives, code complexity, introduction of cross-origin oracles are all real problems. More so for some implementations than others of course.

        False positives made it annoying. False negatives made it useless. Cross-origin oracles made it dangerous. Web developers assuming it did something and security researchers working on bypasses to show them wrong made it expensive. This isn't a haiku, sorry.

        Why was the Microsoft one controversial and not the chrome one? Or is the chrome one considered controversial too?
