I see 2 way to do this. A company (and PM) sees demand for the feature and they include it, ot it is forced by regulation.

A lot of these companies that originally had open standards formed with huge amounts of VC money and they prioritized growth over everything else. Then when they reached a certain scale, investors valued profitability and they slowly squeezed and monetized users until all of those open standards features were gone.
