While I don't disagree the ford racing filter may be better, to imply that those using the standard Fl-820s filter are not properly taking care of their engines is asinine. There will always be some "better" product, be it connecting rods, oil filters, or shifters. That said, at a point, it simply becomes overkill.
There are thousands of hard driven 4v mod motors out there that have been using the standard fl-820s filter for over 100k miles without any oil related problems. While the FRPP filter may be better, there is no evidence that I have seen that indicates that the standard motorcraft filter is not good enough. Most cars do not spend their life at the racetrack bouncing off the rev limiter, and given how frequently most owners change their oil/filter, there is absolutely NOTHING wrong with using the standard product. If you want to use the more expensive one for piece of mind, feel free, but don't chide others for not falling prey to some desire to purchase products that are overkill.
