You're nitpicking on a hypotethical situation, with set outlines for the events that happen in this scenario? What the f*** man. We all know it would be even worse than the scenario put forward, but that's not the question here at all. The question is if you'd accept a renaming of the club for success, using Red Bull as the example in this hypotethical scenario. The scenario of the question would be the same no matter how you replaced the company/new owner at hand. Say a big sheik comes waddling in with tons of cash, but he won't spend it until we're the "Newcastle Magpies" because so many clubs have "United" in their name and he likes Magpies. It's the question that's important here, not the potential buyer.
I just do not like red bull at all so that was why i gave that response but to answer your question properly, disregarding the new owner completely, no i would not accept the renaming of the club for success.
