Nobody has any proof that Gibbs "jacked the prices up" for the alliance. What was said by FRR is that the costs associated with it were continually rising to stay competitive and it didn't make sense anymore to keep the doors open. Barney ran that team without any major sponsor but his own company for years without a Gibbs alliance. If Gibbs was "forcing him out", Barney could have done a lot of things to remain competitive like, switch manufacturers, form an alliance with another fast organization like SHR, Penske etc. I'm sure they looked into that and recognized it's just as or possibly more expensive. Barney had a choice, he chose to close the shop and dissolve the team.
