This is a toy industry trend nicknamed "slicensing." Industry trades have covered it in recent years.

As mentioned in the article, different licenses are extended for different product types. "In just one sub-category, the [Fortnite] license was sliced to give Moose Toys figures smaller than 3 inches, Jazwares figures at 4 inches and 12 inches, and McFarlane premium figures at 7 inches and 11 inches. From a collector standpoint, it can come down to different strokes for different folks, but for some kids, parents, and other toy buyers, the choice can be confusing and overwhelming."

With Loyal Subjects BST AXN, they're at a 5" scale that is relatively non-standard, so they may have the license only for that product class. For brands like TMNT, the other major collector-friendly licenses are NECA at 6" and Super7 at 7". Playmates also does a 5" scale, so I don't know how those licenses work together.
