I envision them kind of like the SCP foundation or fictional grimdark governments.
The top brass are very cold, and don't give two shits about morality or human lives due to their level of separation but have essentially calculated out the steps that need to be taken to make the Backrooms safer and more habitable.
Meanwhile, most of the work is outsourced to junior researchers with no licensing, who essentially are just random people who got someone to sign up on their internet form or are just going to have to die themselves.
Things like minor and finite levels just have pages and reports whipped up and left as is, but things that are more anomalous or difficult to explore start to work their way up until they reach the head of the MEG and have a full-fledged investigation with every available resource.
I thought that the MEG was like a few groups of 6 or so people connected over the internet.
