I think the mags were a means to an end for sports washing and other political issues. There was never any real interest in the club as a whole, just a tool for a particular objective.
It reminds me a bit someone told me years ago about Blackburn Rovers and the Venkys. He said that the Venkys bought Blackburn because they saw other nationalities, Russians, Americans, Chinese, Arabs, owning football clubs in the EPL and thought "India should have an EPL team as well, India shouldn't be missing out" so bought a team in an English town with a large Asian community, thinking they'd become "India's team". But the Venkys knew nothing about football, running a club or the fact that indians interested in football already had a team to follow and wouldn't switch allegiance just because a team is owned by their country. Their mismanagement of Blackburn meant that they were never successful enough to attack newer fans in India.
I think the Saudis were similar. They wanted a team because of the Abu Dhabi lot at Man City, the Qataris at PSG and all that profile having a high profile club can bring. They wanted a team in arguably the most glamorous and high profile league in the world and were sold a pup by Stavely. They thought that it would be easy to buy success at the mags and it would dazzle people enough to make them look good. But it's not worked out that way and I do think they've lost interest in them. It's like buying an expensive car, buying a Jaguar is nice, but if it's mixed in with a bunch of Bentleys, Ferraris, Aston Martins, Rolls Royce's it ends up being a bit "meh". Unless there something to make it special to keep, you're more likely to get rid and forget about it.
