This is nothing new, something similar happened to me 9 years ago.
I had just started contributing to wikipedia, a couple hours daily, then after about one week an admin decided one of my article title was typographically wrong, after a couple silent reverts from him I got to his personal discussion page to ask why and he brandished some arcane internal rules. I checked and he was wrong so I told him so but he refused to acknowledge this and suddenly I was faced with a bunch of people picking on me. I was followed everywhere i contributed and all my edits were reverted by seemingly fans of said admin who also showed up to gang vote against me in all attempt at resolving conflict.
So I went to the public wikipedia space to ask for help and discovered said admin had silently modified the internal global wikipedia policy to reflect his view and it's all downhill from there. I started receiving threats and at this point I was spending 4 hours daily on wikipedia but barely contributed a thing to the content anymore. After a bunch of ineffective bans I worked around, all my contribution were deleted on ground that I had no right to add content while banned.
Then came the messages from people experiencing the same situation who supported me because I stood up, I got tipped that a bunch of admins were discussing me on a secret page and escalated the issue until it reached jimbo wales himself who dismissed the whole thing as he said he fully trusted his admins.
Then I discovered that other people went through the same process before me, I wrote an article on the importance of newcomers for a healthy wikipedia long term and the bias of the power structure and a weakness of wikipedia that would allow a few individuals to ruin the whole project. For this I received a permanent ban from all wikimedia project and a request from the top of the power structure to delete all my contribution to wikipedia side projects, wikitravel just deleted everything no question asked.
So i did the same thing others did before me I replaced a key article of wikipedia with this very story that happened to and reverted my change so now this story would live hidden in a page history inside wikipedia and stopped contributing to wikipedia to do something worthy of my time instead.
back then wikipedia was already a totally different thing that what it pretended to be and imho the problem wikipedia has cannot be solved with a better editor.
