I see that Guardian story has the World Health Organisation as saying that " 'consistent and correct' condom use reduces the risk of HIV infection by 90%." In other words "they aren't 100 per cent safe".

Ninety per cent protection is a lot better than zero protection, but there's still quite a risk involved if those WHO figures are correct. One in ten.

But how is it damaging to point this out? How does it make it less likely that people would use condoms to reduce the risk of infection? It would just mean that they'd be aware of the risk that was still present.
