Does Rick Hendrick not own Hendrick Automotive Group? If so then he is using his money to sponsor his drivers.
If he doesn’t, you might want to tell them to update their “History” page because it’s largely a bio of Rick Hendrick:

Whether it’s money in his personal or business bank account, it’s still money he controls and checks that he has to sign.
The fact that you won’t acknowledge this simple fact is astounding. He could pull that money out of business and claim it as profit, he could reinvest in some aspect of the business, he could even use it to invest otherwise in Hendrick Motorsports. It’s his money.
You can’t even praise Rick Hendrick without his fanboys jumping down your throat.
