Installing open source software on phones is becoming more and more difficult. It used to be the case that bootloaders were generally unlocked or unlockable. That is no longer true, including on Android. Google is also planning on banning APKs from unregistered sources soon.

We need end-to-end encryption on phones to have reasonably convenient privacy. We can definitely lose that, and open source software won't help.

Worse, once phones are locked down desktops and laptops can be locked down as well.
