I can’t imagine software engineers caring about this at all. The only people that care about UI theft are C suite IP clutchers. SWEs generally love being able to use each other’s work. Copying UI by eye has been SOP since the dawn of computing.
As someone who has used multiple vibe coded internal tools: you will care when you use these tools and encounter strange bugs and missing features.
The human touch is visible in the way your features work just like in vibe coded art and games it lacks intention.
