What is the ruling on reselling free or paid products that a person owns under a PLR (Private Label Rights) license—which allows him to dispose of the product as if he were the owner—at a price he determines?

If the products are owned by the website and it has permitted their acquisition and sale, or if they are free and their owners have permitted their acquisition, then it is permissible to acquire, sell, and profit from them, while being gentle with people. However, if the website obtains copyrighted products without the owners' permission, it is not permissible to sell them, because they were not acquired through a permissible means. Copyrights and intellectual property rights are protected by Islamic law, and it is not permissible to infringe upon them.
