Sure, but how does any of that resonate with the general public?
"Apple is using Facebook's front-end code library" isnt exactly a gripping headline or tweet.
You can read the source code to either; its not as if theyre secretly embedding tracking into every React/Angular app.
Ok. I mean you can ask that to Tim Cook :) If not optics it’s about ego. Again, if Apple hates FB/Goog then why use their frameworks when there’s dozens of other alternatives.
