Loose rivets
"I almost started this thread after reading the BBC 'paper' on my FireFox tab. I didn't because it was filled with a LOT of technical misinformation. In particular, they'd gone to the trouble of nose angle drawings but as was so often the case, got muddled with simple pitch and AoA measurements."
That's grossly unfair to the BBC.
Firstly, the article simply reports on the judgment of some individuals whose views are widely accepted as relevant. I'd be interested to know which parts qualify as "technical misinformation".
Secondly, the infographic you object to has been kicking around for a couple of years. While it's an oversimplification in that it uses the term "angle" without explaining whether it's AoA or pitch attitude, that's perfectly reasonable given (a) the target audience and (b) the fact that the distinction is arguably irrelevant in the context of the MCAS failures.
