From what I can tell the "tar-and-feather thing" is outrage directed at Slack and its CXOs, rather than the poor guy who happens to be reposting a message from the CPO.
Please don't let your moderator's concern for injury to individual people blind you to the fact that the outrage triggered by outrageous conduct is directed at the outrageous company and its officers, rather than at individual folks who aren't in a position with any real power.
I don't see how my comment above could be interpreted as any sort of personal attack or tar-and-feather behavior towards the person I replied to. This is a discussion about a bad business practice at a major company, and that is what these concerns are voiced against, not any one individual person who is acting as a spokesperson.
I interpreted it that way based on lots of past experience with the dynamic I wrote about upthread. I believe you that you didn't intend it to come across as hostile! The problem is that intent doesn't communicate itself, especially in short critical comments. The way I usually put it is "the burden is on the commenter to disambiguate" (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...)
I apologize for using your comment as a place to hang a whole generic thing about mobs and whatnot—I certainly didn't mean it about you personally (or even your post) - it's a shared group phenomenon for sure, and I could have made that clearer.
