From a quick glance, these sites appear to be tiny "companies" that probably saw a nice site and decided to copy it rather than think up something great for themselves. They are probably not taking away any measurable business from you via their copies sites, so any time you spend "calling them out" or even drawing more attention to them is just a waste of your time.
Go think up the next great design for them to copy and focus on making your own company better instead of putting down the others who decide to take a shortcut.
