I don't see how scientists starting businesses and making the articles public domain are connected. Having the articles freely available is good for encouraging discovery, communication and learning. I don't see how that would significantly change the equation for protecting your business, as we assume the article was already available for 30 dollars. If a 30 dollars fee is the only thing that stops someone from stealing your idea, it is either a bad idea, or your competitors don't realize it's a good one.
