That does seem to be the reason why the Weinsteins wanted to make the film edgy. (The plot of the Fraggle movie was revealed in May 12, 2008. Sony bought the film rights to the Smurfs in June, a month later.) Looking back at their first project with JHC, the Unstable Fables films, they were all just kiddie CGI films. No digital puppetry. I think Willystein thought that CGI was Henson's only output so they may have a desire to make the FR film just like those three films.
