I would seriously doubt that DAZ or any other provider would encrypt products in such a way that they could not be edited like you say. I'm not sure how they could to be honest, especially since PAs often need to get inside products and figures for morphing, editing, and other means of content creation. Their reasons would most likely be either to deal with piracy or to ease the installation process for new users. Should we never truly have access to the products we buy, you can rest assured that I and many others will be raising hell with any store that goes that route.  :)

Really wouldn't worry about that though, a lot of us are making it clear to whomever we can that any such service should be an option if at all possible and not the only method. Again, I don't speak for DAZ, but I do try to make my opinion heard there.

I do not speak as a representative of DAZ, I speak only as a long-time member here. Be nice (and quit lying about DAZ) and I'll be nice too.
