Wikipedia also tends to suffer from fiefdoms, where even seemingly low-controversy articles become impossible to edit, as someone has decided that article is now their personal pet and they'll spend an absurd amount of time undoing and preventing other people's edits.

The same applies on a larger scale with moderation. There are plenty of poorly-sourced database-like stub entries for STEM subjects, but try to make a page on a "softer" subject and there's a pretty good chance someone will try to nuke it with WP:PROOF, WP:NOTE, and/or WP:OBSCURE if it isn't perfectly fleshed out in the very first draft.

If you encounter that, you can possibly get help to get those articles unstuck. People are not supposed to keep fiefdoms, much of policy prevents it. (and someone with a bit of practice can call in help and clear it up)
