Apples to oranges. Craftopia got specific licensing to utilize that system in their game. The maker of the mod that got taken down would have had to procure similar licensing in order for it to be valid. If they did not acquire that license, then they would be in violation, and would be taken down as a result.
And honestly, to think that TFP would have taken down a mod like that is a bit of a stretch. The mod author wasn't even selling the mod, and they were not making money off of the mod as near as I can tell. The Vroid templates were licensed though, and as are the templates that you purchase for yourself. The interface to utilize these templates is licensed and requires a paid subscription. If the mod author did not acquire the necessary rights for it, then it would be taken down.
Whether you want to look like a human, or a common Vroid is your prerogative. Quitting a game just because the character interface doesn't support your decision is your loss. It is basically the equivalent of boycotting Mario Cart because you can't play it as a pecan pie.
In any case, your issue is completely unrelated to this thread, and does not need to be discussed here further.
