Hello and welcome..IANAL and I do not speak for nor work for FF inc....but......What is being talked about and discussed in those threads is about a very specific type of selling NOT selling models along with their respective textures....The current EULA DOES NOT prohibit any type of texture selling...If you have a license for the app, you also have a license for the textures to do with as you wish....
Also if you create your own textures those belong to you.....
This is only my opinion of how I see the situation and is not to be taken for legal advice....
Stupid things happen to computers for stupid reasons at stupid times!
