No I won't be watching it. It is just a family disagreement which in a lower-middle class setting would be a non-event to everyone else.
A younger member, after reaching the age when he is expected to settle down, decides that he doesn't want to join the family firm but to strike out on his own. His wife doesn't want to join it either, unless she can be on the management board, preferably with a casting vote.
On being told that they will start at the bottom like everyone else and conform to company policy, they flounce out and announce their intention of starting afresh in another country. However, they mean to use one of the parent company's marketing labels for their new firm - which doesn't go down well. An employee leaving, say, IBM, wouldn't be allowed to use marketing material from IBM. That is business etiquette.
An opportunity to join a major TV show to talk about how badly-done-by they are gives the wife the opportunity to use her professional skills at eloquently portraying emotion (which she may or may not be feeling at that moment) and use past traumas. This is to contrast that (deliberately?) with the older "stiff-upper-lip, do it formally and don't fall apart" traditions of the more senior members of the firm so as to emphasise her point that she is modern, open, put-upon and "right" and they are hidebound, cold and "wrong".
I daresay it will give her career a helping hand to spend a while on a high-viewing site discussing how she took on the world's most famous establishment, but I think I'll give it a miss.
