You have chosen a very very poor example in calling out Meta Ads. I can assure you that the entire org has a massive magnifying glass over it with insane amounts of data analysis, every % change in revenue is absolutely attributable to exactly what group brought it about whether it be DC hardware, ML teams, or backend infra. It is the lifeblood of Meta with many billions flowing through it of course it isn't just being cowboy'd with random changes that have undefined impact on yoy revenue.
