You don't, I'm not aware of any vendor that FORCES you to buy their charger, and it's not part of the spec as far as I know. Op is complaining about a charger bricking something - the solution is: buy the approved charger from the vendor. They've tested it, they're telling you it won't brick your device, and I'm confident if it does, they'll replace the device. If you DON'T WANT TO, buy third party. But then don't whine or blame USB-C because you DID buy a cheap charger that bricked your device. That has literally nothing to do with USB-C and everything to do with being penny wise and pound foolish. He's blaming USB-C for something that has nothing to do with USB-C.
