Then we should take your word over mine. My assumption was that those A/B tests will lead to products that do increase the numbers they were measuring (retention, conversion,...) at the expense of enshittified UX (up to the point of things feeling objectively broken, like notification badges re-appearing for the same items, settings that reset after user changes, search results missing,...). At least that was my explanation for how products by major tech giants like LinkedIn, Facebook, Outlook,... could end up being shipped with such flaws. What would you say?
