I think I'm not quite so charitable. To me there's a big difference between using some templates or UI libraries (e.g. Bootstrap or Tailwind UI) as they're intended to build a home page that isn't particularly novel, and shamelessly cloning the design of an existing home page. I'm a big fan of focusing on the product itself and treating the home page as "get the message across with as little design and engineering work as possible," but do the former rather than the latter.
