"The idea that private companies can just do whatever" distorted the other comment into something ideologically inflammatory (which the site guidelines explicitly ask not to do), and took the thread on a generic ideological tangent. Those routinely turn into flamewars. Posting something that predictably induces a flamewar is flamebait.
I was also surprised but then I read up on the rest of The comments from that account in this thread as well and think that it something like that might be justified.
I also read the rest of the comments linked as examples and some of them where obvious to me and some were not.
I'm not a native speaker though and I realize dang has a huge advantage there as well as access to see detailed voting statistics to see what riles people up.
