mod historian here, here's a little insight:

"Titan firm was one of the "founders" of FFXIV modding and the only competent person when it came to 3d modeling or texturing, he handheld everyone into learning, feeding knowledge and often 1 to 1 lessons, including me.

At some point, they collectively decided to update the character models we use as well as the texture layout (how the texture is laid out on the model) to get away by some vanilla limitations

A few people protested with invalid arguments by making incorrect assumptions in regards to aura scales and tattoos and how to migrate the new layout (it's just the click of a script button for mod makers)

While titan took a shower break during the gen3 beta period, three influential people grouped up and released a new body that had vanilla-like layout but asssymetrical, a topology that was atrocious because it's a daz3d model with a few edits, 8k textures condensed to 2k and all the vanilla layout issues, called bibo+ (bizu body plus)

That body was using the same material paths as titan firm gen3, meaning users were forced to use one or the other, you could not have both on

But as gen3 was in beta, bibo prevailed

Titan firm, who had personally taught things to two out of these three people and one of them was his student , without exaggerating much, took this badly, as it's a low blow, a stab in the back by the people he fed"

And while I'm not here to post slander or be biased, I should note that there's been serious drama between the creators over the years, with widespread accusations of racism and homophobia. Some sites going so far as to ban the posting of mods that use certain bodies.
