The android which your r mentioning here is AOSP.All third party rom use like lineage is etc.this as they don't come with Google apps.The android that Google Samsung etc provides on their mobile are from android alliance group.These contain proprietary drivers.The Aosp based rom was used by a hardware vendor was Nokia before the brand phased out to Microsoft.News has mentioned that also but the Biggest spyware is windows 10, Google Android and chrome browser but nobody cares. It seems we are trusting USA more than China.
We should promote Linux but govt is sleeping. Our BOSS Linux has not got updated from long time and there is no law to regulate Google Android. Android as a open source should not come with Google apps pre-installed in mobile like the Chinese people hv in their country. People should hv other choice of Android also.
