Breach of Contract, sounds like to me.
I’ve always loved that Jane Fonda’s partner in her touring hate-America company in the early 70s (Donald Sutherland) has a son who is now the voice of Bank of America.
It could well be a breach of contract.
Part of why corporations spend so much to sponsor a stadium is so that, at any event held there, the announcers will say “here we are at (fill in the blank) stadium”, to get their name out there as advertising.
It may well be that the contract states that any event held there must mention that they are at Bank of America Stadium.
