An in-depth look into the technical details of the blocking would be interesting to read. Another point is that the data from Atlas VPN seems somewhat unreliable:
"Atlas VPN research team analyzed and ranked 85 countries in terms of VPN usage in 2020, 2021, and 2022. The VPN penetration rate was calculated by summing up VPN downloads by country and dividing them by the country’s population. The VPN download data is extracted from Google Play Store and Apple App Store using the Sensor Tower service for data in 2020 and 2021. The data for 2022 was extracted using AppTweak. Download data includes 45 biggest VPN providers."
