It's a tough one and I actually agree because what else did we expect? I think there's a romanticism that still lives on in in football of the Dave Whelan type owner but they don't really exist anymore unless you go into the lower leagues, if you are a big CL club you're either a hobby for some rich oligarch, a sports washing project or just a business, geared to make as much profit as possible for it's owners. We fall into the latter, along with Arsenal, Pool, Newcastle and most PL clubs.
The Glazers' have removed themselves from the day to day, the hiring and firing and (as far as I can tell) anything that goes on at the club. United are portfolio company for them, they care about us but not because they love the club or the history but because we are their investment. Most of our gripes are more with Woodward and the slap dash approach to hiring, particularly managers, that has come after SAF.
Personally, it angers me at how the club is run but this is a bigger issue with sports club ownership/monetization and is ironically much to do with us as fans - the beauty of investing in a big club like United is the massive fan base don't disappear, most stick with the club for life. The Glazers' are just doing what most owners are doing, they just have the biggest cash cow. I guess at least they seem consistently frugal across their franchises, have to feel for Arsenal fans who have the same situation as us with an owner who puts nothing into the club but is building a huge stadium for his NFL club with his own money.
