There's a flaw to this argument, it's not comparing apples with apples, in fact, let's take Apple! If you want to not buy an iphone, you can, I'm guessing you can't stop being a Spurs fan and choose another club?
You can say Man City, no one outside the club thinks they're anything but a state run, financially doped club who cheat the fair play rules and win at literally any cost. I hate Liverpool but I take solace with them winning the prem over them.
I am saying you do not know who comes next, ENIC could do their due diligence and it could still go to shit, let's say Amazon take over the club, but it turns out Amazon are knocked out of the market by a Chinese competitor, the club loses it's big rich sponsor and it goes to crap. That is part of your risk model, the next owner can still get it wrong with just plain bad luck, as can ENIC in fairness...
It's a good hypothetical debate but it is never that simple - the real world is nuanced, complicated, complex and other cliches!
