As for why the downvotes: I assume because, as per the discussions in the thread you linked to, the consensus was that those claims, particularly the CP accusations, were rather overblown, so repeating them may be being seen as pointless, adding nothing useful to the current discussion. I've not seen the images in question, links in the thread require a GitHub account to view, but they are not said to be titillating unless you are _really_ trying to be titillated.
The author has apologized for this rather tasteless joke which he didn't expect to blow up as much as it did and has moved on.
Doesn't change anything about the projects tech and this recent achievement (of a one-man pet-project mind you)
Does it though? I remember once opening Notepad++ after an update, where the changelog itself never mentioned that its first start will behave like a virus, open a new tab, and start typing messages in solidarity with the victims of a french mass shooting.
That crap ain’t cool
But again, he has been rightfully scolded for that, has apologized and pledged to do better. If he doesn't, well that's bad but then even more people will stop using the project.
I just don't see any real value in bringing missteps of a project up in every subsequent discussion, especially if it's a storm in a teacup like this one (it was a hidden easteregg, not some auto-poster).
