Of course not, but because payment models affect your companies goals it definitely affects every other aspect of how you run the company, including customer services. Fairly simple logic, complete lack of annoying phrasing.
The difference is that in a P2P game we expect something for that money, we have long term (ie next patch(es)) expectations and the developer has to work to fulfill those if they want to see more payments. In a F2P game once they have their money there is no expectation from the players, or less of an expectation. Sure they expect new content, but not to the same degree people playing a subscription game do.
