Interesting post. I do consider a lot you’re saying is correct. But PLR has always been a “base” to create your own product, whether it’s ebooks or WordPress themes. When it comes to saving time, PLR has done it for me. I never just download a PLR product and use ‘as is.’ I always use it as a starting point to create something 100% unique again.
With creating a PLR HTML course, that would be good. I cannot say I’ve seen one that offers detailed lessons. I suppose that’s up to the PLR creators and not the marketplaces that release PLR products from other vendors.
