I understand exactly what my rights with any software licence I purchase regardless of the company: Adobe, Marvelous, Pixologic, Luxology and DAZ. You can't pass those programs around either legally because they have that stated in their EULAs as well. If you want your family to use a program or content, you have to buy for each or purchase a licence that covers multiple users. When you buy a product you agree to that licence.

If these negotiations exist, then where is the "Nonprofit" vendor license at the Daz store, where is it here on Renderosity? On software sites like Adobe, they state straight up what the price is for schools. Why is it held secret so that few even know that it exists, esp. those for whom English is not their first language and therefore can't even understand the EULA? (Hell, I have trouble understanding it as well in some areas but thought I thoguht sure I understood everything relevant.) This is especially true for non-Daz originals since there is no way to contact a PA directly for a non-profit license. It also makes it easy for a company to cheat non-profits since there is no transparency of transactions or set prices.

When exactly did this start? The EULA that I have ever fully read for any program is that it is for either 1 residential household/apartment room or (usually) a max of 3-4 computers at a single business. (I rarely read the EULA because it's alway so damn long and I never imagined it would include anything like this. Usually I just read the privacy statement. I've read the EULA on the old DAZ exes several times and don't remember reading anything like that.)
I am aware of the distribution thing-- I thought the "no redistribution" thing for 3D models only applied to selling it, letting someone put it on their machine as well outside of your household, or not transferring ownership.
