      It's a very long race, and we're not at the finish line yet. If CSP paints itself into a corner then you will be proven right.

      CSP will only be used by a few, big companies. All devs I talk to do not understand it and thus cannot use it securely.

      Today. But when it's simpler? What if there's more education? What if there are more tools? Framework integration? It's not static.

      CSP had +5 years for that. We do not need more complex security mechanisms, but fool-prove ones.

      Not every site uses postMessage, or video, but as part of the platform it lets interesting & valuable things be built.

      I am happy to be convinced of the benefits of CSP, but no one is able to show me any real XSSes where it helped.

      : Hard to prove a negative. *shrug* I’m all for burning CSP down, but let’s replace it with something first. @hillbrad @randomdross

      we still pay for bugs prevented by CSP in VRP, but to my knowledge none has been reported yet.

      We have data that >70% of XSS would be mitigated by nonce-based CSP. Ignoring this is disingenuous

      70% of Google's current bugs that are considerably different from bugs you see everywhere else.

      Bugs from hundreds of applications on many stacks. If you have better data, please share it.

          I have better data from http://goo.gl/Mbr0Wq . But only on DOM-XSS and it is out-dated

          it would be possible to collect it again, but it is a lot of effort.
