I always did think it was odd that a USB-C cable that wasnt Nintendo could break my Switch.
Early devices were things like the OnePlus 2 [0] and there were plenty of phones out before the Switch even hit the market in 2017 [1]. There were some issues with standards compliance, sure, but the market had vastly improved by the time the Switch had come out.

Nintendo messed up, that's it.
Every device in my room except for switch supports more than one voltage config. Wondering why on the earth switch decided to handle voltage setting like this.
Usually, pd charger will label their supported voltage config. And you can read that label to find out whether a charger will work with switch or not.

I'm not saying that's the case for you, but USB-C is a minefield and I've seen some weird things happen with USB-C plugs.
So there are non-compliant plugs, but if your device breaks just because it sees a regular PD VBUS voltage (5-20V) then it means that it was designed badly - either through ineptitude or foolish cost saving.
To be pedantic, I believe that only applies to USB-C sockets; AFAIK, a USB-C plug (like on a USB-A to USB-C cable) can in some cases put out 5V (but only 5V) before detecting a sink.
> but if your device breaks just because it sees a regular PD VBUS voltage (5-20V) then it means that it was designed badly
The standard was designed so that devices never see anything over 5V unless they ask for it, so why should a non-PD device (for instance, a mouse) care about it? In some cases (like a USB-A mouse plugged into a USB-A to USB-C adapter), the device might even have been designed and built when USB was 5V only.
That fried another device when I plugged it in.
This is non compliant in the EU, but when I reported it to the responsible authorities, they didn't feel like doing anything about it.
We are talking about a charger that can fry any device and potentially cause a fire, coming with a product aimed at people with babies, that's clearly non compliant to be sold in the EU, and they are doing nothing at all. Pretty shocking if you ask me.
I could put a USB-C connector on a device and have it not even try to do any USB protocol over the wire. If not being careful about pinouts, it could be super easy to destroy either device if plugged into some other USB-compliant device.
One problem with EU regulation (or at least most regulations; a few have union-wide regulators) is that you're really quite dependent on whether your national responsible body is any good.
For something like this (assuming it's sold union-wide and not just in your country), it might actually be useful to notify the responsible bodies on _other countries_ (once it's actually investigated and recalled the recall should be union-wide).
