Current leakage on newer MacBooks

I just got a 2020 MacBook Air, and noticed current leakage (a tingling feeling when touching the metal) which I never had with any other MacBook before. It's only mildly disturbing, but I suspect it's probably not healthy for the computer, either. Searching the internet, I found a number of suggestions pointing to faulty grounding of the household wiring. That may be true for some, but the wiring (in our house in Austria) is fine - properly grounded.

The problem is Apple's power adapter. The one that came with my new MB Air was 2-pronged - no ground connection. The power adapters up to now have always had a ground connection. The solution was simple: I replaced the plug on the new adapter (easily slides off) with one from an older adapter, and now there's no more current leakage. I can't understand why Apple ships a problematic plug with the new power adapters, when they used to ship a better cord, which is healthier for the Mac.
