No, it's not acceptable. Others have reported similar issues with other brands of cartridge filters, which seem to have more issues with fitment than spin-ons (obviously).
Issues like this should be reported to the manufacturer so they can investigate and rectify the issue. In the mean time, use brands that you know work ... it's a free country (so far),

That's because spin-on filters are way more common than cartridge filters, so when someone starts talking about oil filters but don't specify they are talking about a cartridge filter, the reader will assume it's a spin-on. Posters need to say they are talking about a cartridge filter if that's what they are talking about.
