If it signals a move to exclusively pay per view that would be a bad thing IMHO. While it might increase revenue stream not sure how it would play with team sponsors if audience viewing figures were to reduce. Evidently there has been a drop in the global TV audience from 600 million to 400 million since 2008. [ that's a not inconsequential 33 % drop!]
I saw F1 as historically having a European vibe. Most of teams are European and mainly UK based. I suspect that if Liberty wants to increase market share to the New World that might change. Nothing wrong with that just a different mind set. Think American v Association Football. Both hugely popular but a completely different experience.
