USB micro-B is still everywhere. A lot of random devices still use it as a charging port. I got an older Amazon Echo Dot that used micro-B for power, although the one I got with a clock uses a coax power connector. Last year I got a Roku Express 4K+ and that has a micro-B port for power. I found an image of the back.
I've also got a few USB mini-B devices. Some older external hard drives including bus or external powered. I got a Blue Snowball ICE microphone, which is still being made. I do remember when the Motorola RAZR V3 used it, but it didn't really work universally with any of my other power adapters other than ones specifically for that device which had a captive cable.
Sorry I should have been more specific, micro USB-B 3.0*. The non-3.0 one I can understand still being used because it's so small.
