Yes, the Raspberry Pi models are a little confusing, especially with the '+' versions and PCB-revisions. But I don't think the purpose of the parent comment was to say that it was worse than others, more of a heads-up to someone looking to order a model to take a second look and verify the specifications.
How is this any different than the general SBC market? You could make the same point about the "Raspberry Pi" which has:
* Raspberry Pi model A/B
* Raspberry Pi 2 model B
* Raspberry Pi 3 model B
* Raspberry Pi Zero
* Raspberry Pi Zero W
> Also a lot of the boards can only be powered by a DC jack, not the onboard MicroUSB.
Almost all boards can also be powered via 5V GPIO pins, so you can wire a DC jack to that to avoid using micro USB.
