Based on what?

Gasket, when is the last time you've seen a properly installed oil filter fail at the gasket? So if the OP did 6500 miles in the first 22 months then I would expect that he could change the oil and go another 6500 miles on that filter and it would still look great when cut open.
You guys seem focused on construction and durability of its materials. Obviously anything silicone would be fine, and the synthetic filtering material would be fine. That's not my issue.
But we're all looking at the same pics here, or specifically the same one pic of the filter media. Yup, it's a dirty oil filter. And unless someone pulls it apart and inspects the media closely, there's no way to tell how that filter is doing, and even then, that's not very scientific. In these cut-open threads when dirty filters are posted that are not physically bad (like torn Puro pleats or squished Fram carboard ends), there are always comments like 'You could have used it longer', and/or 'It would have gone another OCI'. A filter on a clean engine could be filled with small particles meaning it's at the end of its useable life, but since it wouldn't look like it was packed with crud, people here would still post 'It still looks good!'.
Looking at that one pic, you can come to a few logical conclusions: 1) the filter media held up fine, 2) the seam is still ugly but apparently did not fail, and 3) 440's engine seems to be relatively clean inside judging from the lack of crumbs anywhere. That said, I don't think it's reasonable to assume that the filter has plenty of life left without taking a much closer look at what's inside the media which is not something you can do by just looking at a picture.
So what criteria is everyone using here? A pliable ADBV, no rips, and not overflowing with gunk means it's still good to go? That seems like an awfully low mark to hit. I just don't understand where the comments come from.
