The problem is that most of the time, threads like that quickly devolve. They go from intelligent, thoughtful conversation about an issue to people ranting, throwing insults, personal attacks, etc. Or just armchair financial experts giving terrible advice. (Par for the course with that particular subreddit)

Money can quickly become a heated discussion. I'd assume behind that thread is a wall of much worse comments that had to be removed. Removing them all gets exhausting, and sometimes it's better to just lock the thread and move on.

I really don't think they care one way or the other about BoA.
