Unfortunately the noises from the likes of Lineker, Shearer (not that I personally care what they say) etc are clearly in favour of the changes. All the premier league clubs voted for it. It needs the majority of premier league fans and probably a fair number from the championship to dissent against the changes as they are the ones with the large social media presence that could force a rethink like when the Super League was proposed.
The EFL and National League clubs can kick off all they like, and I hope they do boycott or whatever extreme it takes, but the FA know the efl clubs need the money and the FA hold the cards.
