The problem isn't manufacturers discontinuing drivers, it's that Apple changes the requirements for a driver to operate with each release of it's OS making it necessary for driver manufacturers to produce new or updated drivers. For a company like HP or Canon with 10s of thousands of products in it's portfolio that's untenable, and with OSX only being a minuscule portion of their user base it becomes a huge waste of time and money.
