I'd hope no one actually thinks this about the cap not applying at all, but there ARE some cash poor owners that have or have had some trouble with ponying up large bonuses for marquee free agents that require guarantees and a significant percentage of the contact paid up front. The organizations with cash rich owners have had an easier time circumventing the spirit of the salary cap and using it to their advantage.
This is a significant advantage with a tangible on-field effect.
I have a difficult time believing that's going to be an issue for anyone who can pay the current price of admission. What could Bezos even afford that an owner worth $50B couldn't easily afford? Not like these guys are cutting personal checks for these things. We see it with Tepper in Carolina, who is one of the richest owners in sports but still demands public funds for everything. The fans largely hate him.
I'm not naive enough to think anyone who can afford the team isn't going to see it largely as an investment, but I think we all want to see someone who prioritizes a winning culture and happy fans over strictly the bottom line, and I don't know what people see in Bezos to think he's even a little like that. He has the money to make the Washington Post the greatest news publication, with the best material, and available to the most people, and he's still running it into the ground, cutting costs left and right. He has more money than he could spend in several lifetimes if his job was just to spend money, and he's still fighting tooth and nail for more tax breaks. I have yet to see where he cares about anyone other than himself. If a "good" billionaire even exists, he sure as hell isn't one of them. No matter how much money is in his account, it'll never be enough. And I don't think I've seen him show any interest whatsoever in football.
If his ex-wife wants to buy the team, that'd be awesome though.
