Can you point out exactly what they are ripping off?
GW did not create the Minotaur or many other fantasy creatures.
AoW minis are a bit larger in scale.
Aesthetically they are different and far from confusing.
Looking at the AoW and GW Minotaur
Horns are different
GW horns are much longer look more like a Texas Long Horn.
AoW looks more like the horns of a Steer
Muscles on the GW Minotaur are excessive, lumpy, some are semi-sphere, and over all more cartoon-ish.
Muscles on the AoW Minotaur are less bumpy and more of a smooth curve. Less muscles and a more realistic look to muscle tone. There are also bulging veins present.
Fur on the GW models are more feather shaped.
AoW model is more organic and wild.
the heads are the BIGGEST looking difference in aesthetics.
The GW Minotaur has a head that is more football shaped. There is no real resemblance to a bull head at all.
AoW Minotaur has a head that looks more like a bull with wide open nostrils.
If you are looking for aesthetics being ripped off, it's not there.
There is a stronger resemblance among the GW Orks and AoW Orcs, but for good reason, the Sculptor for AoW was a sculptor for GW at one time, but tjhere enough to prevent any sort of IP Lawsuit.
This has always been my favorite comic strip in regards to people jumping the gun a GW lawsuits, in particular, the Fantasy range which GW borrowed most of their ideas from other ranges. Tolkien, Conan, DnD, etc.
