I dont see what is the issue about british broadcast being biased a bit towards british drivers, unless Sky F1 becomes official F1 TV (which is what I want to happen). Also Davidson biased towards british? He's top class unbiased and insightful commentator who can explain things technically with some flavour of right excitement. Ted K has aspects he should improve on or change (yeah tabloid nature in short) but info gathering and presenting ability he's way above average or I cant really imagine anything better than that, so bring someone comprehensively equal or better than him if replace or diminish him. Herbert is petulant and tends to be emotion/impression/tantrum driven, has positive side but really dispensable. di Resta is really 2nd only to Davidson, his composure and ability to see and grasp big picture is top notch, F1 needs someone "boring" like him instead of party happy people like Pinkham and Herbert.
Pinkham is charming but she's more like fan representative than professional, in terms of observation ability just no match to Brookes who is truly excellent.
The issue that's common for almost all (maybe especially Brooks, Pinkham) however, is tendency or abuse to make leading questions or question to ask for consent in interviews, like "must be happy" "must be gutted" "xxxx, isnt it?", "xxxx, right?". You get to learn in schools that these sorts of questions distort the outcome so absolute no-no in whatever field either engineering or journalism or whatever. Seems they forgot it completely.
Brundle deteriorated quite a bit, Croft/Lazenby is meh, dispensable but wonder anyone better than them? so necessary/lesser evil for the moment.
What's by far the worst, truly astonishing, is the guy at F1TV, who seems to have joy to speak by placing comma or pause by every phrase, or word, just, like, this. Just can't stand it. Also he only speaks about and see things by cheap mental analysis or imagining like must be feeling this way, xxx is that way so must be like this or whatever, never technical, never analytical, never objective. He simply totally lacks knowledge, that guy is truly awful, almost frightening.
