Upon re-reading the tweet that ostensibly triggered the takedown, I think I actually agree. Originally I read the author throwing out the insult "dirtbag left" as an indication that they were in opposition to the leftist message presented in the documentation, but with closer reading I see that this person certainly considers themselves to be on the left.
That the complainer uses "dirtbag left" disparagingly is quite telling, given that this style of left-wing activism started as a reaction to bring leftist politics back to its anti-capitalist roots, and away from the sort of hand-wringing politically-correct tropespotting nonsense the complainer likes to tweet about.
It would be better for humanity if we could distinguish between those who profit by destroying it and those who resist them. Defending IAP is not leftist.
