The website is in Russian though. The author probably knew that because he had to use some online translation tool to go through the purchase process.
Fun fact: the Kazakh government decided to replace Cyrillic with Latin for the Kazakh language. Apparently the process is supposed to end in 2025, but I have no idea how widely adopted the new alphabet is at the moment.

Not much. Most publications and websites are still using the old alphabet, including the most important government portal which is used by pretty much everybody: https://egov.kz/cms/kk
I rarely see it on anything more substantial than ad banners and propaganda posters (like "don't litter" and "vote for our beloved leader").
