so your argument is that microsoft keeps on hand enough accounts with high enough karma to downvote you and then also upvote you when you call out their conspiracy so that they dont seem to be downvoting you?
Actually, the likely scenario is that Microsoft employees make up a sizable portion of the HN user base (relative to smaller companies) and when an MS employee sees something antagonistic towards MS, they downvote.
Apple, Google, Microsoft, and Facebook to varying degrees all have the same phenomenon on HN. It's not the PR team, it's the eng team in their spare time.
your life must be a constant wonder
