As a French guy who grew up playing CS 1.6 on an AZERTY keyboard, I have a feeling that the people who made this website are either a generation above or below Millenials.
Because it doesn't make sense: you don't make a website in English, with prices in USD... while expecting users to have an AZERTY keyboard.
I'm a millenial and can say you can absolutely make a site with i18n + currency conversion without knowing what keyboards people use. Especially Americans, who are much less familiar with "other markets", because companies can stay within US customers for so long.
It is a bit weird. As someone from Belgium (we also use our own variety of Azerty) you are very frequently reminded that you're on a weird keyboard. At least for someone who games, you wouldn't make ZQSD the default. It's the first thing you do in every game, change WASD to ZQSD
Another Belgian here, the first thing I did when I started working is switch to International English keyboards. Some employers wanted me to use local keyboards but I always managed to convince them to let me get another one in the end.

We even had a meme and tshirts about it: https://wiki.nofrag.com/Jte_niaue_q_lq_Kqlqsh
