In that respect, I believe Ubiquiti are in a definite minority.  This is a feature that you have to actively disable in the stock kernel if you don't want it.  I've heard that Ubiquiti tend to use a rather old kernel for, you guessed it, reasons of hardware vendor intransigence regarding open-source support.

As a direct counterpoint, I'll point to TP-Link as a vendor who actively advertises Airtime Fairness as a feature on many of their current products, and not buried in the gritty details of cryptic standards-compliance nomenclature, but as a bullet point on the slick slideshow that consumers are presented with.
