And what do you think "properly engineering" a flexible arm to handle increased stress might be?
I've talked to these companies - it isn't a secret that disc forks are stiffer to handle the stresses. Forks aren't complicated.
And stating a fact isn't "impugning" anything. If I say a 23mm tires has lower rolling resistance, it isn't impugning the tire to point out it is slower on rough roads. That's just physics.
