The sport has headed off in a different direction over the last couple of years and there is so much focus on non racing factors, fake rivalries, focus on team principals, and now a focus on drivers girlfriends watching from the pits. Would a breakaway series be aimed at traditional F1 fans or the OK magazine crowd? I know which one will provide the most revenue but that probably wouldn't be the series that would survive long term.
Do you not remember the constant shots of Mika's wife 25 years ago? Or all the attention Ron, EJ and Flavio use to muster bickering in the press? Frank was always shown sat in font of his TV in the garage. Traditional fans are normal people. Most people like the extras, some don't. The idea drama and intrigue is only for certain crowds is a crock. If it was just about going in circles and racing it will be boring and not very popular, as demonstrated by countless grassroots motorsports that offer great racing but go unwatched.
Doing the opposite of whatever Liberty does sounds like a save bet to longterm success.
Long term success in any venture is based around financial security. In that regard, F1 has never had it better.
