Anyway, you could also say that for example Quickstep don't prioritize any of their riders but also slow them down by making all of them riding
disc brake bikes.
But in comparison, UAE actually prioritze Pogacar by letting him ride v-brakes in the toughest mountain stages of the Tour.
The main reason you see riders using particular equipment is what bike companies want to advertise to the market at the moment, and they intentionally exaggerate the gains from aero vs climbing frames etc. Few years ago cobbles designated bikes were pushed very hard by the companies so 3/4 of the peloton was riding Roubaix on such bikes (and then Hayman won it on an aero bike, which was supposed to be unrideable on the cobbles). This year, most of the riders rode P-R on aero bikes, beacuse that's the bike segment which sells best now.
