No need for a conspiracy. This is hackernews. Not reddit. I doubt they are spending their marketing dollars here.
As for the breaking of rules, dang has commented, and I’ll take responsibility for my actions.
You should just read them when you have a chance since they address the stuff you bring up simply and directly. Don't start meta-threads about votes. Don't accuse fellow users of shillage, brigading, astro-turfing, etc, without evidence. If you suspect abuse, email the mods. It's all in there, along with the rationale.
