Hence: "cherry picked". You don't have to pick ALL the parts if you don't want. You can still compare a full framework and the 2-3 items you cherry picked though as methods of getting web apps done.
Who said those who use Angular will just use Angular only as it comes upstream and won't pick and/or substitute a few libs for third party ones either?
Of course it's not forbidden. It's just confusing to say you're comparing React to a framework, when you implicitly include things other than React in the definition of React.
