On human rights, no regime is without sin. The US in the Middle East, the British didn't exactly cover themselves in glory in India when they were powerful.
The Glazers bought Man Utd via a leveraged buyout (see
https://en.wikipedia.org/wiki/Barbarians_at_the_Gate:_The_Fall_of_RJR_Nabisco) because they didn't have the money but borrowed money using Man Utd as collateral to finance the sale. Since then, the costs of financing that debt plus the money that the Glazers have taken out of the club have SEVERELY constrained our football. There is no chance of this getting any better under the current regime and we will remain where we are, a ways behind the very best.
The only way to get out from under this burden is to be acquired by an entity which has the money (last valuation was greater than 3 bn pounds) and will, at the very least, stop the transfer of money out of our club. Very few entities can do that, MBS is one of them. We should be grateful for such an opportunity.
