The account has been suspended for a while, but for whatever reason that's not displayed on the profile itself (can be seen at https://github.com/Larhzu?tab=following). Repo being disabled is newer, and, while annoying and realistically likely pointless, it's not particularly unreasonable to take down a repository including a real backdoor.
Taking down the repo prevents more people inadvertendly pulling and building the backdoor so that makes sense. They should have immediately rehosted and archived the state at a different URL which makes it clear to not use it.
