Encountering an irritating number of devices that are charged/powered via a USB-C port but that don’t work with a USB-C pd charger (only with a USB-C to USB-A cable).
Bonus irritation: a device with a USB-C port that works with a PD charger only if the cable is plugged in one orientation, but will work in either orientation if connected to a USB-A charger. (A Phillips rechargeable pocket work light).
I’m hard pressed to think of another “standard” that has as many incomprehensible and unpredictable ways things can be incompatible as USB-C.
@mattblaze I happen to deal with a lot of standards professionals in my day job, and I can tell you that what you amateurs might call "incomprehensible and unpredictable ways" they would instead refer to as "flexibility."
@carlmalamud Those same professionals think you're a terrorist.
@mattblaze sticks and stones, etc, etc. They can call me whatever they want.
@carlmalamud @mattblaze I call you a hero, and I talk to my kids about what you do when they ask about my heroes. So, I suppose it's a counterpoint?
@willyyam I'll take that. Your kids are the jurisdiction which I'm trying the most to impress. Please tell them I said hi and seek their approval. :)

@carlmalamud @mattblaze Mmm. Flexibility. That's a goodun.

My favourite word when used with standards is "profiles".

We all know what that means. Each manufacturer gets to pick and choose which parts of the standard applies to their product.
