Earlier quoted context omitted.
The W3C's failures pale in comparison to what I hear of the ISO MPEG process, in which companies compete to put as much of their patented technology in the codec standard as possible without any regard for coherence. ISO is worse than the W3C.
ISO at least still releases real standards with multiple implementations. Web standards by contrast have basically become a pretense, as the actual standard is defined by Google’s implementation.
I mean, to some degree that's true, but that's not anything the W3C can do anything about. It's just the nature of the browser market at this time.
As an example, C++, also an ISO standard, has notoriously few full implementations, and as a result C++ is largely defined by "what GCC/Clang accept" in practice.
