The best way is freeing Android. Android should be the "Mobile Linux". What should happen is that EU should ensure that people are allowed to side load and unlock bootloaders and that all apps are compatible with alternative ROMs. All dependencies on google play services should simply be made illegal and all apps should be fully compatible with AOSP.
If we can't get this we will spend the next 10-15 years in mobile dark ages. Mobile Linux may never get enough tracking to be supported the way desktop Linux is.
