There are a couple of legitimate reasons. Raising the issue internally only brings ire and attention by admins and shadow groups. I tried doing this via the WMF village pump , technical pumps, admin pages and only drew more attacks.

Raising the issues externally comes off as petty, because the “evidence” consists of 50+ pages of inane bickering on talk pages, community post , etc with no clear narrative or verdict. It’s a unique community that leans heavily on hyper-bureaucratic and bespoke debates.

I could share > 5 severe cases that required weeks of effort to “resolve” . It would require nearly as much effort for anyone to draw conclusions from.

There are some index pages of some of the more notable conflicts & debates. If you can indicate that digging that up would be worth my time to help you understand more, I may be willing to help you out.

I was mostly looking for specific interactions to dig in to, but if you have a link or two for me to take a peek, we'll both know if it's worth it soon enough. You don't have to dig deep straight away.
