I think all the cases people have found with Google Maps are issues with upstream data providers. There are much more subtle ways to catch theft that do not have a negative user experience (the angle an alley connects two roads, or the curve of a highway).
While Dbrand definitely seems keen to pull some stunts, the difference between this versus that is that at least in that case, Dbrand still had to put in the work to replicate the PlayStation 5 faceplates. It's not as though Dbrand owns the inside of a phone: had Casetify done the work and simply created a similar product to Dbrand, this wouldn't be a lawsuit. It's because they stole the end product from Dbrand, which would be more like if Dbrand stole Sony's design files to make the faceplates. Whether what they were trying to pull with the PS5 was actually legal or not is another question, but also, in my opinion it certainly wasn't a dirty theft either way.
It would be unsurprising if that was all intended from the start as a viral marketing campaign. I don't remember hearing that they ever got in any trouble with Sony, and they're pretty infamous for "taunting" others to sue them (and similar stunt language like "our lawyers told us we couldn't make this") in all their marketing.
they significantly changed the "darkplates". The 2.0 lawyer-approved version doesn't even have the distinctive "fins" (or collar or whatever you want to call it) .
Casetify almost definitely never looked at actual internals of actual smartphones, so there was no way for them to know the difference between faithfully replicated details and easter eggs.
Maybe same effect but sounds like the purpose here was to include jokes for their customers (otherwise they probably would have included other things than jokes that can be identified by anyone with a brain)

I believe they had to end up changing the design in their 2nd iteration...

It seeks like Casetify ripped off Dbrand in the laziest way possible.
