Yes you are reading right. Stealing add-ons. Maybe you can say why stealing when add-ons are free … The problem is that many authors of add-ons take another, already finished one, modify it and release it as their own work ... without giving credits to original author. This is not correct. Why I'm writing this. Maybe you know two skilful Czech authors
Maac and Marfy, their textures are often plagiarised so they have contacted us, if we could delete these add-ons released on our page without their permission. We do not agree with stealing textures from add-ons without giving credits so we deleted that add-ons.
Here is part of their email :
We do not forbid using our textures! But we think we don't ask too much if we want to know about it before and if we want to have a little notice in accompanying text document.It concerns these add-ons: E.I. M113A2, IDF M163 Vulcan, M2A2 Desert and UN HMMWV.
