The real obstacle to degoogled mobile OS's is not software (AOSP exists, pmOS will become usable soon, etc. etc.) but access to online services of all sorts. Google Play is a focal point for distributing the official "app" for your online service of choice. But if a whole country goes Google-free this can definitely change.

In practice, without access to Google Play people just use third party app stores like F-Droid or just download the apk from the web like on a normal computer. It really doesn't seem like that much of a loss for Turkey.

You would have to force Android manufacturers to also provide Google free versions of their products. One only has to look at Microsofts history to see that backroom deals will keep alternatives of the table unless forced.

Or the history of Android itself - Google forbade manufacturers from making competing alternatives as part of its confidential licensing agreements: https://www.reuters.com/article/us-eu-google-antitrust/googl...
