Except the EOMM isn't about the matchmaking process itself. It has to do with what happens when you're IN the match. Doing too well? Sorry but we have to dial you back a bit. Not doing well enough? Ok, you'll get a bit of a boost. It's all about keeping players happy and satisfied with their game results even though the gameplay is just manipulated. And happy players may tend to buy more microtransactions according to the big companies.
I can't say that this is definitely happening in 2042 but given that it's happening in Call of Duty (and supposedly Apex) and that the paper was co-written by EA employees I wouldn't put it past them.
There's no question that these big companies are just predatory and seem to care less and less about the games now. My recent gameplay examples I mentioned just raise suspicions.
