There's a minority of fans that do that, bit i don't think we're all guilty of it. There really isn't an excuse for not doing the research and finding out who does what. Its not overly complicated. To put the blame at Hoylands door for all recruitment at united, justifying it with a list of signings that Everton made during his time at Everton as well is mental. The guy is the Chief scout at United and seems that was his role at Everton. Furthermore, Everton look like they had a DoF as well. So his role was even more diluted there.
I'm not for a minute suggesting that this summers recruitment went well and Hoyland will have played a part in that. I can't say with certainty that we had a comittee doing the recruiting, but in Wilders previous reign we had something like a committee and Wilder talks now about contract negotiations being out of his remit, so its a fair guess that the manager / head coach is involved with identifying players he wants and there are a number of people in the process analysing whether they would be worth the risk. I don't doubt that Selles would've had some role as well.
What is clear from the summer is that whoever was involved, the process failed, we relied too heavily on future investments through data and AI, Bord was involved, but he no longer is. Bettis and Wilder have made some comments in recent weeks / months.
We fans can sit here and have a go at anyone we want, but if you're going to call someone out for doing a shit job, at least make sure there is some accuracy in the justification...
