"What about a manufacturer's website for drivers?"
You keep raising that. Let's look at it.
Where do these manufacturers make their money?
By selling the H/W that their drivers support.
What would happen if they poisoned their drivers?
They'd burn their main business. (Remember how quickly HP had to row back after the shit-storm they raised by playing silly buggers with their ink cartridges.)
Why would they want to do that?
