The Brick-Gate issue, where many switches where bricked, was not an issue with generic chargers, but specifically 3rd party docks. And, as it turns out, the issue in that case wasn't on the switch side, but the manufacturers of the 3rd party docks, that used 9v on a normal signal pin (cc) [very much not spec compliant], which destroyed the pd chip inside the switch: https://hackaday.com/2019/08/04/the-not-quite-usb-c-of-ninte.... There have been few -if any- reports of switches being destroyed otherwise.
