Not true. On Samsung devices, at least the Exynos ones, you can install FOSS operating systems like LineageOS or /e/OS. Of course there are still proprietary blobs for drivers, but that's no different than running GNU/Linux on an Intel microprocessor.
It's from AOSP, so any device close to the actual Android baseline should support that. This means that you can enter that mode from LineageOS as well.
You know though that the United States have "taken down" governments before? Americans do not have any right to feel superior on this issue in the slightest way
Lol that's Lemmy for ya
