The problems is that vendors use "locked down devices" as an excuse to limit competition.

Suppose you have a "locked down" device that can only install apps from official sources, but "official sources" means Apple, Google, Samsung or Amazon. Moreover, you can disable any of these if you want to (requiring a factory reset to re-enable), but Google or Apple can't unilaterally insist that you can't use Amazon, or for that matter F-Droid etc.

Let the owner of the device lock it down as much as they want. Do not let the vendor do this when the owner doesn't want it.
