This is also a good perspective. One thing I was thinking just now: at some point, side loading on iOS will be a thing. I wonder at that time we can truly use an iPhone without an account at all (not even to install stuff), but my guess is, considering their track record, they will do the wildest malicious compliance possible…
I never encountered this I have to say. Will bookmark it and save it for later when I need to double check this. But from what I see, FP 4 and 5 can be locked again after custom ROm imaging. This is actually good news. Thanks for the share!
