Well I'm not sure it takes an expert to master a plug.
But I'd understand the hate if it was universal (pun maybe intended), but everyone that hates micro-usb seems to adore usb-c, while I feel like it's potentially much more fragile. When handling usb-c I always use a lot more delicate care than I ever did with micro-usb. Mostly because even though I'm pretty good at soldering very tiny things, I'm not confident I could replace most usb-c receptacles without messing it up.
You say that as if solving grid storage wasn't one of the most important problems humanity faces right now.
