> OpenGraph tags would never have been necessary. Small correction: XHTML2 had the Metainformation Attributes Module [1]. That then became RDFa in (X)HTML, practically the same syntax and processing model. Facebooks Open Graph stuff is claimed to be RDFa. When I tested it then their Parser did not really do RDFa processing - other CURIE prefixes for the same URI weren't recognized, if I remember correctly. But in effect Open Graph meta information would have looked the same in XHTML2 as in todays WHATTF HTML. For your other argument I agree. WHATWG (and dumb modern style of development) reduced the democratising aspect of the web. But of course the people of WHATWG word for billion dollar companies, which want to have a moat to centralize behind.
