> but isn't it a lot of code and testing to implement the personalization UI? Most of the stuff cited as example come from additional features changing an existing behavior. Allowing to disable it would be overhead, but really not much I think. Another example: Youtube started to automatically translate “foreign” video titles. Having a “never translate anything ever” toggle in settings would smallish, there is no other UI impact, and they must already have that kind of setting internally for testing or legacy purpose.
