If it's a business, then it's a business full of tyrannic monopolies. Science publishers are essentially leeching public money, because government funding goes only to people who publish through those publishers. That is a perpetual loop that is impossible to break, since scientists are incentivized (with public money) to publish through established journals. That is not 'clean' business like any other.
OTOH, open access doesn't mean that one has to do away with all the established journals, just that they have to make their content open to everyone. There are other ways to cover their operating costs, like charging for publishing (a better model, in which scientists have an incentive to choose the journal that offers the best value/money).
