Compact adapters like 20W and 30W adapters dont have three pin connectors bro. I didnt notice any such electric shock or problems with my macbook air m1 model till date. My building also have good earth connection as I dont experience any such earth issues till date with other accessories too.
We can use third party spike busters to prevent any short circuits or electrical damages to the appliances and electronic gadgets we use.
It is possible to experience such electric shock due to adapter too. But as its USB C adapter, we can ofcourse change or use different branded adapters with the USB C to USB C cable.
Apple may not fix this by replacing out adapters right now bro. But we can take some measures as suggested above to prevent any such electric problems and shocks happening to our devices.
