Sysadmin work tends to be invisible and thankless - until something breaks.
Having been in their shoes most of my career, I try to resist the natural urge to get annoyed and complain when things break. Especially if it's rare and they get fixed quickly.
Don't judge work only by errors and mistakes - it's more fair to consider how well (or poorly) problems are handled.
Also consider: in Mastodon-land, often the admin work is a hobby. If it hobbies stop being fun, people find other hobbies...
