The access to the Telegraph article is very client dependent. On my tablet, using Chrome, I could read it. On my desktop, using Firefox and clicking the link provided, I could read it. On my desktop using Chrome, it was blocked. On my desktop using Edge, it was blocked. It also seems to depend on whether you accept or reject cookies but I couldn't be bothered testing all the combinations.

Once you understand that not all browsers and devices act in the same way you can understand that people who can read it and people who cannot read it are not doing anything different, but their equipment is. There is no right or wrong here.

What was it you said, John? "A bit of IT-literacy is always helpful". As someone who worked in high-end IT design, support and testing I thing the phrase "A bit of IT-literacy is dangerous" would be more suitable.
