I am no fan of the Glazers, most certainly not.
But I note in the leaflet above, these words, "An ownership that is systematically starving and killing the greatest football institution in world football, for greed".
Sure they are killing it. But starving it? And for greed? How can anyone claim they've starved United when you have spent more money on transfers in the last 10 years than any other club in the world? You sit at the very top, having spent more than anyone else. How is that "starving" you exactly?
Seems to me the reason to get rid of them is just sheer incompetence, not financial starvation. They are either hands-on, and accountable for the many mistakes and serial underperformance. Or they are hands off, but have appointed the wrong people and not fired them soon enough. In which case they are also accountable. Any which way, IMO fault for your predicament lies with the Glazers. But you cannot accuse them of starving the club. Just accuse them of being utterly useless.
(And yes, I know the Glazers have not been funding your spending with their own cash reserves - it's all United's money that's been spent, but nevertheless they have allowed you to spend it.)
