You do have a valid point, however the parties involved were reimbursed for their efforts. Jackson paid the Beatles millions of dollars for their songs. I'm sure Fogerty took some sort of quitclaim in return for those songs (David Guard took a lump sum in excess of $300,000 in 1961 in lieu of future revenues and agreed to not to sing the arrangements nor songs that he had written for the Kingston Trio. His former partners continue to collect the revenues from those songs even today.)
