In general there are three incentives at Big Tech: * Develop a platform, framework, standard, or policy that influences (hopefully positively) how other developers work. * Ship an end-user feature behind an A/B test that proves it has meaningful impact on KPIs. * Make some organizational annoyance that is popping up on your management chain's radar go away (migration ticket, SLA breach, etc). Making a UI good for the sake of being good is not one of them. No one cares that you delighted the customer. That only ever happens to the extent that people give a shit beyond their incentives, or the organization is small enough to have outdated and irrational management practices.
