Those are fairly broad statements without anything to support them. I do not recall ever seeing an OEM or Wix filter that was allergen rated but the 3M home filter I used in this DIY is. 18 months of usage without an issue shows that it doesn't hurt any part of the ventilation system.

Before the hack there were over 30 posts in this thread from folks that had done this DIY and were happy with it. I understand that some people prefer a custom made filter but that is no reason to malign a proven DIY version of it with fabrications and alarmism.
