Yeah, I totally agree. The only annoyance I see is that you have to experiment with what cables and power adapters through trial and error to find what works with particular devices. I mentioned in a different reply in this thread that there ought to be some kind of consumer-friendly labeling on these things, so that you can see at a glance what will work with what.
You don't have to. You can. As the previous comment mentioned, nothing stops you from buying all the accessories and cables from Apple at a premium like you used to with lightning.
Funnily enough, this is why the only USB-C chargers and cables I carry around are my Apple ones - because they've been the only ones that I've been able to reliably trust across all my other devices (including USB-C Apple devices).
