The source for that blog is http://dgui.wordpress.com/ who gets his source from the Register article back in April. Strangely he had a different opinion in May http://dgui.wordpress.com/2011/04/30...-meego-hinted/

For whatever purpose the WSJ were given a story to print, and to me at least, it makes sense. The memo from April quoted in the Register article and others, made a mention of staff from the Meego team moving to the meltemi project. That would be the Meego Harmattan team, that was previously the maemo fremantle team, and others previously.

Maybe it's for future disruptions, or maybe they've taken a look at maemo fremantle running on the n900, and the popularity amongst reviewers of meego harmattan on the n9, and thought, "hey if we get some low end hardware [as maybe the n900 can be considered in the modern market context] and stick this linux crap on, maybe we can shift some devices", and then leaked that info around the time that Tizen was announced.
