Facebook seems to say, you have 1 week to update your sign-in integration code to the latest version (or I guess they get cut off from Facebook API or something?).
Apple says you must support Apple sign-in, or you won't be allowed on our App Store, without with it's nearly impossible to get your app on an iPhone.
Google says guess what we want based on our vague emails and meaningless responses, or we remove your extension/app from the store, making it nearly impossible to use on Chrome.
Geez, it's like Microsoft is the good guy of the tech majors here.
