The same website the OP links to, which is an Australian site, has a page that includes the text, "Vitamin D deficiency may be a greater health concern for people with naturally very dark skin, as it is more difficult for people with this skin type to make vitamin D.".

It's unclear why an Australian site would be going into the question of who is "suited to" live in the UK.

My point is that the Australian perspective on the matter invites no controversy.

The indigenous population of Australia is dark-skinned and has access to all the sun it needs in order to stay Vitamin-D sufficient.

Coincidentally, the COVID-19 mortality rates in Australia are low as well, though some might prefer to chalk that up to the strict lockdowns.

I mean, the low case rates could be due to the lockdowns, not sure about mortality rates unless you're comparing it to places where the ICUs have become overwhelmed.
