Say you developed some website/service and someone literally stripped your frontend/UI code and just replaced logos/theme colors.
Is that enforceable to protect or is this something like "Just happens, build new features to stay on top of copying"
Didn't happen to me(yet), there was a job that I backed out of after it was clear this was the intent "copy this site, replace their logo with my logo, change from red to blue, etc..."
