Duplicate content found on techradar.com

Hi,

Here I found duplicate content on a famous domain techradar.com

I want to ask why google is not taking actions against all his 6 duplicate languages, these duplicate content are up since July 2019.

Published approx 50K duplicate pages on each country, details are below

<link rel="alternate" hreflang="x-default" href="https://www.techradar.com/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-GB" href="https://www.techradar.com/uk/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-US" href="https://www.techradar.com/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-CA" href="https://www.techradar.com/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-AU" href="https://www.techradar.com/au/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-NZ" href="https://www.techradar.com/nz/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-SG" href="https://www.techradar.com/sg/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-MY" href="https://www.techradar.com/sg/vpn/cheapest-vpn"> <link rel="alternate" hreflang="en-IN" href="https://www.techradar.com/in/vpn/cheapest-vpn">


Also is this the right way to publish your thousand of pages just by adding a country directory in your URL like "/au/" "/uk/" etc...

as per my knowledge this is the google quality violations that, publish single content on multiple urls
