They also came into a Roma that had been put into a financial hole by Monchi's very terrible transfers (some of which are still dragging Roma down financially because Monchi had signed some bang average players to absolutely insane contracts) - while I think part of their problems at Roma have been due to them not really knowing a whole lot about football or running a football club, they've also done some things that Roma fans like & they've also had their hands tied by some of those dealings before they'd bought the club.
They've got a sort of mixed reputation among Roma fans. I know a couple of diehard Roma fans in Rome irl and one of them absolutely hates them the other thinks they're not so bad given the circumstances they found themselves in... although has questioned their decision making. The truth is probably they're somewhere in the middle of those two views. For as unhappy as many Roma fans are... they did win that silly new European trophy pretty recently - which means even Roma fans unhappy with the state of their club have seen more joy in recent years than most Everton fans have for the entirety of my life.
And realistically speaking, their struggles as owners of Roma are probably a really good learning experience for them as they try to build Everton up from the pits that Moshiri & Kenwright have pulled one of English footballs biggest clubs into. For as bad as the Friedkin group can potentially be, I think it'd be a far cry from what Moshiri's tenure as Everton owner would mean for the club.
