Well, it seems to be pretty much random whether an article is true or
not; where they're just recyling blogs and press releases they're OK,
but you might as well read the blog or press release.  Some articles
are just fine, but it's like reading the Eye: unless you're an expert
you don't know which articles are accurate, so you have no way to
extract any information.

It's not bad at all.  There's certainly nothing in there to support
the contention that the Raspberry Pi software is just a wrapper around
a "huge proprietory blob".  The GPU is just a peripheral, albeit an
important one.  Of course it would be nice if the closed binary for
the GPU weren't needed.
