I think it's also worth noting that the Nintendo Switch and I think many of their previous consoles have been jailbroken to high heaven. So there's an overhead of maybe not being able to use Nintendo networked services, but you are able to "own" the device more. People have gotten Ubuntu running on a Nintendo Switch IIRC.
This is not an optimal solution, but it is more of a solution than, for example, the (maybe I'm wrong) lack of jailbreaks for iOS that are usable (eg. tethered jailbreaks are more work to maintain).
Like I mentioned, tethered jailbreaks are not restrictive and from what I've gathered and require specific hardware and iOS versions (https://www.reddit.com/r/jailbreak/comments/1go8wy4/what_is_...). Sure, you can maybe jailbreak the latest iOS on specific devices, but it's a lot more restrictive in selection, and various devices have various levels of being able to be untethered.
Meanwhile, old Switches have a hardware vulnerability [1] and all newer ones can be jailbroken to their fullest with a modchip. Such pervasive coverage doesn't exist for iDevices to my knowledge.
