so you mean unauthorized apps wont be running on android?

That is indeed the plan and what is meant by "starts restricting FOSS apps" (which is an incorrect statement but whatever)

However, making that happen outside of its app store will require Google to take a page from Apple's playbook and flex its muscle in a way many Android users and developers could find intrusive. Google plans to create a streamlined Android Developer Console, which devs will use if they plan to distribute apps outside of the Play Store. After verifying their identities, developers will have to register the package name and signing keys of their apps. Google won't check the content or functionality of the apps, though.

(...)

Google says that only apps with verified identities will be installable on certified Android devices, which is virtually every Android-based device

What was argued was that people can basically just compile/download and deploy their own apps via development tools. Which is unfeasible for the vast majority of users for skill reasons but also, as I said, likely to be blocked by google themselves in the not too distant future.
