I'm just tired of the 'everyone follows their immediate incentives while the system stays incoherent' as the de facto reality. I think shedding some light over the actual mechanics would maybe make someone consider 'perhaps we shouldn't allow our acquisition team just turn off their brain and choose the default to cover their bottoms; maybe vendors are worth more decision investment via actual thinking instead of performatively ending up on the default choice after a little ritualistic game of "eeny, meeny, miny, AWS"'.

I think it's worth pointing out that Jeff Bezos would fight this tooth and nail from happening in his companies. He popularised 'process as proxy'. Yet AWS as sold to external enterprises is the exact proxy Bezos warned against internally. Do what Bezos does, and even what Bezos preaches, just don't do by default what Bezos sells.
