Not with my money. You taking my money without specifically asking means that I will never, ever do business with you again. (And that I'll specifically warn other people against dealing with you.) "It's better to ask forgiveness than permission" is not a universal truth to be applied to every aspect of startups/tech work. It is often a good idea when there's a lot of bureaucratic red tape and/or you need to get approval from other people about things. This is a very different situation: you're charging your customers ~4x more than they originally paid for something automatically. Are there other companies that do this sort of thing? Sure. Maybe it makes sense financially, but it's not a good way to treat your customers.
