I used to hold an FAA Inspection Authorization for aircraft. I had a standing bet on the airfield where I hung out that I could find a technical violation of rules, regulations, good practice, etc., on any aircraft. I never lost that bet. Does that mean those aircraft should have been grounded, and the operator punished? No. All rules and codes I've ever seen have been written by human beings and leave a lot to the imagination or interpretation of the inspectors -- who in general do a decent job of protecting the public safety. Granted, some jobs don't look pretty, and we all can find ways we might have done things differently, but that doesn't mean that all "pig slop" candidates are a threat to the public. In spite of government efforts to the contrary, common sense occasionally prevails.
