But they won't be forcing anyone to use content as stated in this quote.

"<DAZ_Chad> We're also happy to provide content only to those with no interest in DAZ
  software. We want that content to be the best available.
<DAZ_Chad> Ideally users that come to DAZ from one specific background (either
  software or content), will learn the advantages of expanding their useage of DAZ
  products. And we want our software and content to work extremely well together.
<DAZ_Chad> As we all know, to make a 3D animation, a single person typically can't
  do it all from scratch, unless you have a year or so to devote to the effort.
<DAZ_Chad> So regardless of skill level or background, we see software as two great
  solutions that work well together. But they don't have to.
<DAZ_Chad> We just want you all to keep doing what you do so well. Keep it up! "
