whether or not those packages should have been affected is another discussion, but it appear it probably had more of an effect on other open source packages and perhaps the work of small mom and pop companies rather than huge corporations.
The deletion here was more complex, and most likely a human was assigned to review user reports to GitHub Security, who accurately determined it was a defacement from someone claiming to be the author’s credentials.
Turns out the author was the attacker, and with that confirmed, it appears that their access was restored so they could proceed with it.
I suspect this is how it played out as well. In fact, there was a lot of people on Twitter who were questioning whether the author really got suspended since he was posting to github a day or two after he posted his suspension picture.
