Not sure how him defending some actual testing data is "making it up"

And the million mile Ford van I'm sure hasn't had special filters during its life either. Generally the vehicles driven to these mileages are used in an operating profile that is conducive to significant mileage accumulation in a short period of time. This is a relatively easy life when compared to short trip stop and go with cold starts, regardless of how somebody sells "hard used". Taxis and Limo's are another example, I've seen several 800+ thousand mile Town Cars for sale, I'm sure they didn't get anything special for oil or filters either.

Except those companies change their minds. Heck, the filters they ship with are different than their service filters for example. It isn't like OEM filters are static, they change too, and this could be on something as simple as price. Everything is a compromise in some manner. If the OEM was all about using the best, they'd all have threaded-end bypasses with silicone ADBV's and glass media, but they don't. But often their "high performance" racing versions do, or even their higher tier offerings. Toyota's own TRD filters are an example here, which use the superior glass media. Also, if the efficiency thing was "nonsense" they wouldn't sell their higher tier offerings and companies like Donaldson wouldn't exist. Simply because a consumer usage profile won't allow for the advantage of the product to be realized doesn't invalidate the advantage as "nonsense", but it may mean it isn't a cost effective option for that consumer.

So AMSOIL having Chevrolet on there somehow compromises the validity of the data provided by the lab? You are reaching...

That's an even further reach.

Out of date? Sure, it might be, if the construction of the filters in the test has changed. If they haven't, then the results are just as valid now as they were then.
Questionable? Only if you believe that AMSOIL would knowingly publish falsified information. That would be inviting a lawsuit, so I seriously doubt that's the case.
Meaningless? If the data is still valid; if the filters are still the same as they were then, then the data is far from meaningless, it is some of the only data we have in contrasted filtration efficiency.
Not sure how you've managed to construe that as sad, this seems a construct of your own psyche to be able to obtain closure by invalidating this information.

You are certainly entitled to your own opinions, but if they are questionably based you shouldn't be surprised if somebody calls you on them. Some vague anecdotal allusion to contradicting 3rd party particle count data hardly stands as an affront to the validity of that obtained via controlled laboratory testing and the implication that it should be is ridiculous.
