The filter is easily removed and inspected and re-installed if desired. You might want to keep an eye on it in case the bypass valve in the cap is malfunctioning. A new cap and filter assembly is part number Delco PF458G.
That's unfortunate...or maybe bypass filtration?

Not all miles are equal to all other miles. I figured I was driving nearly the easiest miles possible so I could go 2 OCI per FCI on a top-shelf-ultimate-premium filter (and only stretching the FCI by a measly 5k miles over the box recommendation). Also as mentioned by someone else, I would assume the media (totally plugged) should be able to withstand Delta P at 0 degrees F oil temp and engine redline with a functional in-spec bypass system, a far harsher condition than my engine/oil/filter was ever exposed to)... I don't think that's too much to ask, especially with that fine wire mesh backer.
I think it was a QC defect on Fram's part but we'll never know because:
1) In this or another thread someone sent a torn filter back to Fram that "couldn't be tested because of damage" which would be the same in this case.
2) I tore a chunk of filter media off to shine a flashlight through it (intentional and excessive damage to filter media?) The media was not PLUGGED, I could see light through some areas, but it was less light than I expected to see. In any event I would expect the bypass to relieve enough pressure/flow that the media wouldn't tear.
3) The filter is gone, never to be seen again.
I put a FU right back in it's place because that's what I had on hand and I'm not sweating. I've used several FU filters in this engine (on 8K and 10K FCI) and never noticed tearing before.
Re-stating what I think is your best point: The failure mode for over-loading the filter and causing high differential pressure (e.g. from over 15K miles or just plain sludge) should only be the bypass opening -- Not structural failure of the media.

One good thing about a cartridge filter is they are easily visually inspected before and after use.
I just started using Fram Ultra on 3 Toyota's.
This one make's me want to go back to OEM Toyota.
Hard to believe it's Filter media problem after see so many cut open photos.

Tiny filter to run so long - $7 and zero time as pointed out -
I'll keep doing my turbo Cruze at 7500 - use AC Delco filters ...
