It is? To this day I'm buying new peripherals that only offer micro-USB and come with a cable with regular USB on the other end. I'm talking devices made within the last couple of years. In fact I'd say that's been my experience with every purchase I've made besides my refurbed Pixel 3 XL. USB-C definitely doesn't seem ubiquitous to me.
As I replied to another post: I've gone Type C only since about a year ago.
I guess I should have been clearer to point out that's it's still quite possible to(common?) to buy non-type C devices (you can still buy DE-9 serial devices too), but it's certainly possibly to buy a Type C version of almost anything (external drive/card reader/a lamp...).
