I am currently using a Pureone, but since I bought a ton of Mobil 1 on sale I will be switching to their synthetic line. I have no problem with the P1 and have the utmost confidence that this one I have in use now will be tear free.

For example, an un-torn synthetic or P1/ Classic cartridge filter is except as well as anything made before the first tear date.
*That is a lot of digging.
Im just going to be looking for filters between the two dates that are verified by pictures. I will probably count any Purolator product (Classic, P1, Synthetic), spin on or cartridge, or their rebadges. If it is a quality problem, the rebadged filters have just as much risk of failure as the branded ones.
Easiest way: Start a thread were people post a picture of their untorn filter. That way their is proof and I wont have to go digging through miles of posts like these.
I see your point since their QC department is under the same roof, but adding the filters without the trend tear wont give accurate numbers IMO.
Bosch Premium= P1
Promotive= Classic
That's all I can think of at the top of my head.
QS, MC, and Mopar are all Purolator made, but don't have the same "issues." One could ague the cartridge filters are exempt from this as well. (Several guys here wont use a spin on, but will use a cartridge worry free.) The Synthetic doesn't have the issue either.
If it is a quality control issue or defective manufacturing, failure should be present than in more than one or two styles of filter. IIRC their have been some motorcraft filters that have torn also.

That's probably because they use different media that isn't as prone to tearing under the same conditions.
No. On the rebadged ones I have used the media is the same, but the pleats, arrangements and/or bypass system were slightly different.
Its hard to say how their operations run. We havent experienced any tear-like failures with Motorcraft or Mopars so I imagine something different is being done. IMO, the failed Motorcraft filters that were added to the list looked like they were flawed right from the factory.
I am pretty sure they use a different media formulations for the MC and Mopar filters. MCs are sometimes in service 10k and it has been said here that 10k is way too long for an entry level to be in service. Either way, it is impossible to know one way or the other. I doubt they would tell us.
Just consider what I said. Ill shut up now though.
Either way, itll be interesting to see what you find.
(You can add my none failed Promotive to the list of good filters btw.
)
