Although Volvo or Mann filters are best, I have yet to see where any other brand of oil filter caused a problem. I think you've been BSd about the seal blowing due to an aftermarket filter because that's really not even possible. If the filter clogged, there's a bypass which will still allow oil to flow but it'll bypass the filter, not cause excessive oil pressure.

It's more likely that the person with the bad real seal (which happens after alot of miles) is just trying to blame someone or something. On non-turbo engines, a clogged flame trap or flame trap hoses can cause excessive blowby pressures and that can cause seals to blow. Turbo engines can also have too much blowby if there's a problem with the PCV system.
