Did you read the article? This doesn't seem like the old "Microsoft bullying others into following" story, this seems like legitimate reasoning for the moment.
They are not in a position to bully anyone, just like they were when IE3 came out. So they made IE4 which mopped the floor with NS4. And it still took a lot of time until the momentum changed and IE became popular.
And then they bullied everyone with IE 5, IE 5.5 and IE 6 - like they did (and still do) with Office (OpenXML), SMB, Kerberos and a variety of other products.
Of course their statement is going to be about merit - they've never said "oh, we're bullying here" even when they were. And their statement MIGHT even have some merit - but just like in the OASIS OpenOffice document spec, instead of working with the industry, they arrive late with their own underspecified and alternative specification.
