My guess is that it was downvoted because it violates two of the comment guidelines: > Comments should get more thoughtful and substantive, not less, as a topic gets more divisive. The parent comment is neither thoughtful nor substantive, merely agreeing with the grandparent -- a verbose equivalent of a "This!" comment. A better comment might include the commenter's reasoning, their experiences with other platforms and their pros and cons, or how they have used Ubuntu personally or professionally, for example. > Eschew flamebait. Avoid unrelated controversies and generic tangents. The parent's implicit dismissal of Windows or Mac desktop platforms as un-enjoyable could be interpreted as flamebait, since choice of operating system can be a common point of contention. Hopefully this explanation helps. Since the comment was low-quality but not flagrantly bad, I assume it will pick up one or two downvotes but not a flag, and will sink naturally down the discussion as higher-quality posts supersede it.
