Yeah, as they've said you're taking a tire that's 8 or 9 or 10 inches wide at the tread contact patch and that's your canvas. How many tread designs can you fit in that space? Not many.

Goodyear has been the innovator in odd designs. Just look at the new MT-R/K tire...look at the GS-A.. they like to do one thing on one half of the tire, and then something totally different on the other half. Been doing that for a couple of decades at least. There are pros and cons to this though...tread wear and the ability to rotate being a big issue.

Bottom line is the tire engineers are very limited to what they can do in a small space of tire contact patch. You have to keep noise down and you have to dig into the mud which is why the tread blocks are angled. Less angle means more noise. Firestone specifically uses a 23 degree angle on their tread blocks. This is their preferred way of doing it. They do this on ag tires too. Other companies use less angle at the expense of noise. But you have to give the tire small changes to prevent patent violations, while at the same time keeping the basic formula intact. So that's why everything looks the same.

When I'm looking at MTs (which by the way stands for Mud Terrain...it even says Mud Terrain on the sidewall of most MTs) the thing I'm most interested in is siping because not all MTs have it, price, and how close is that center tread void for noise cancellation?
