My impression of the PPA is that you can try to commercialize what's in it without inhibiting your chances of filing for a non-provisional one before your 12 months are up. I am not entirely sure, but what I know is form the USPTO website as quoted below:
"The provisional application must name all of the inventor(s). In view of the one-year grace period provided by 35 U.S.C. 102(b)(1) in conjunction with 35 U.S.C. 102(a)(1), a provisional application can be filed up to 12 months following an inventor's public disclosure of the invention. (Such a pre-filing disclosure, although protected in the United States, may preclude patenting in foreign countries.) A public disclosure (e.g., publication, public use, offer for sale) more than one year before the provisional application filing date would preclude patenting in the United States. Keep in mind that a publication, use, sale, or other activity only has to be made available to the public to qualify as a public disclosure."
Since PPAs are not examined by the USPTO, I think you're safe in being able to file for a non-provisional patent a year later that would use the information in the PPA. In fact, the non-provisional one would have to build on the prior one; that's part of the premise for why provisional patents were established. (Refer to above USPTO link for further details.)
