Designs and strings are only sometimes covered under copyright.
The elements of a design that are ornamental, utilitarian, or a general look and feel are not covered under copyright but would be covered under a design patent if one exists.
Strings are only covered under copyright if they are a sufficiently original work of human expression. Simple informational messages generally wouldn't qualify.
This was copying many screens, composing layouts and many strings. not a "general look and feel" or one off utility string. Others found parts of the code copied (exact variable names). It would take a court to decide, but I think it's pretty clear cut copyright violation. They gave their agent had access to the EE code, and seemingly asked it to produce a copy. It's not a 1:1 copy, but there was a lot of copying. No clean-room attempt was even made.
If I take the first chapter of Harry Potter and write a new ending, it's still copyright violation. They took many parts.
If they did take sufficiently significant parts of copyrightable components, then yes, it would be a copyright violation. I don't think I saw overwhelming evidence of that in the OP, but certainly there is more to the story.
