I did not claim Apple has any special privileges here. The situation  
just strikes me as an odd conflict of interest. Imagine if, say, Henri  
Sivonen volunteered to edit HTML+RDFa. You would probably be  
suspicious and would not expect him to have the best interests of the  
RDFa community at heart, since his track record is one of generally  
opposing the technology. (Sorry for using you in a hypothetical Henri!)


P.S. For the sake of correcting the historical record, Apple never  
"turned over the Canvas element" to anyone. Canvas started out as a  
browser-specific extension and was not originally envisioned as being  
for public Web content (probably short-sighted on our parts). Then it  
was added to WHATWG Web Apps 1.0 without consulting us, and later  
included in HTML5 when published as a Working Draft by the HTML WG. At  
that time of FPWD we satisfied the Patent Policy requirements for our  
related patents. We have been supportive of keeping it in the spec,  
and have had to make major changes to our implementation to match the  
standard. At no point did we say "HTML Working Group, please take this  
over," it just happened, as with other formerly proprietary extensions  
that are now part of the HTML5 spec.
