Don't assign to malice what can be explained by incompetence:

* new automated UX experiments starts * the UI bot made a change that made the page unscrollable * the experiment has a much higher rate of retention then the control (because people can't scroll) * the experiment is deemed a success by results analysis (no one looks at the page to see WHY) * the experiment is blessed as the new pipeline

Such an obvious business improvement made by Gemini !
