This and the teams are arguing that they supported F1 when things were tight in the last few years through covid and they don't want new teams jumping on the bandwagon and taking a slice of their pie now the sport is booming.
The teams need to look at the bigger picture, there aren't enough spaces on the grid now and if a team was to leave we'd be down to 18 cars which really isn't enough. A new team joining HAS to pay an entry fee of $200m which is divided between the teams to subsidise any losses they may make. The teams want this raised to $600m as they are saying that the $200m fee was agreed years ago and the bigger fee is now a more accurate representation but that kind of number almost makes F1 a closed shop (probably what they want).
Personally I don't see how they can possibly refuse someone like Andretti who will have a huge fan base in America and who are bringing GM onboard as well. Hitech, the other likely new team, have a huge history in junior formula. These teams would be nothing like the last batch of teams that came in went in a few seasons back in 2010. Doesn't really seem right that the teams have a vote on the matter, the FIA should have the only say on if a new team can join or not.
