There's something odd about this. The repo in question is 'nixxquality/WebMConverter' which is where the GitHub notice was sent. However, this is a fork of another repo - https://github.com/WebMBro/WebMConverter - and that parent repo seems alive and well (that is, not disabled, and unchanged, so still titled 'WebM for retards') so why the discrepancy? Did the WebMBro account get suspended initially, and then reinstated, and only the fork felt the need to change the text? If so, this seems like a lot of overreaction based on what may well have been a (well intentioned) mistake on GitHub's part?
According to the link in the commit message, this repository (nixxquality/WebMConverter) was disabled as a consequence of the parent repository (WebMBro/WebMConverter) getting disabled by GitHub. Presumably the parent repository owners also got a message like this when their repository was disabled.
Also, as you've observed: Neither repository is currently disabled.
