Concerning amount of errors on BBC comp. sci. revision page

I wondered "How bad could it be?" and was unpleasantly surprised.

So much is wrong on this page - poor choices on the diagrams, erroneous text. And no obvious ways to suggest corrections.

The BBC does not have technical editors of quality. It is a simple as that. Today they were talking about clots caused by AZ vaccine. During this "technical" article they said AZ as well as all other covid vaccines deliver viral RNA. Doh! https://www.bbc.co.uk/news/health-59418123
