      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.

      And only if it can be globally adapted. But CSP is incompatible with many apps e.g AngularJS

      I find it interesting to see rants against an optional security feature that solves a real problem

          It's just as useful to complain about ASLR or other low-level mitigations ;-)

          Cost/benefit ratio is negative. Ok, If CSP is for free, but effort is better spend elsewhere

          everyone focuses on CSP, no one on addressing the root cause.

          Look at suborigins and isolation proposals ;-) The diff. is that CSP exists and is supported *now*

          There is no secret cabal that kills good ideas to fight XSS root causes. Just not many good ideas.
