Yes, but then the danger is still that people trust websites they open
by using the QR code and not the QR code itself.

By calling QR codes "dangerous" you give the wrong impression, that just
scanning a QR code and checking, what website it links to, is dangerous.
And this is of course not the case. Just don't trust any websites which
get opened using a QR code scan - only view them and do never enter any
personal data there.
