I also stopped using Fram filters due to these poor threads. I never saw Fram filters with this issue until late last year, but I checked three different ones off the shelf one day in a row and they all had massive hanging burrs.
My concern is that, what if a large burr fell off into the inside of the filter while the finished filter was being jostled around during packaging or shipping, and then at first engine start with that filter, the burr gets circulated through the engine? I much prefer clean threads that are free of burrs since we have the choice.
I switched to Denso. Their spin-on filters have excellent threads and they package them with a clear plastic seal over the entire open end of the filter.
