So, they say that the system is evolving, but from these parts of the article I would argue that the ease of contributing (which is the important part) is taking a massive hit:
> "you will no longer be able to click Edit on a page, make and save a change, and have it show up nearly immediately on the page. You’ll also no longer be able to do your edits in a WYSIWYG editor."
> "you won’t have a WYSIWYG to instantly see what the page looks like as you add your content, and in addition you’ll be editing raw HTML"
They had a user-friendly system previously... Now users have to learn GitHub and author raw HTML! - I would point out that not all documentation writers are developers!

Ignoring the fact Microsoft's Github has recently had DMCA insanity, a proprietary frontend, and recently enforced Webcomponents (effectively removing UXP devs who were forced to self-host Gitea just to continue working)... this seems like Mozilla is trying to outsource as much as possible from their own hosting. They also shutdown Firefox Send.
Perhaps Mozilla is having issues / unable afford their own hosting anymore?
Not trying to be inflammatory here. What does it matter if Microsoft has a proprietary front end for Github when all the docs are in markdown?
One example would be it is not possible to even make a PR request on Github as half the GUI no longer works in non-WebComponents browers. If it were open source we could perhaps see what WebComponent feature they think is missing and implement it in the browser engine, as it is they do not have any desire to collaborate and the black box makes it all the more difficult to debug.
Github's response: "... further degradation is a likelihood. I appreciate that this is disappointing and frustrating for you..." - https://forum.palemoon.org/viewtopic.php?p=202146#p202146
