PPAs maintained by the app's devs—as many are—seem trustworthy. It's ok if PPA authors can potentially introduce proprietary content; that's how all software is. The usual solution in free software communities is to file a freedom issue and remove the proprietary content, e.g., remove the wiki link and move the PPA to a "Known Freedom Issues" section.
