Flags aren't for rule breaking, they just mean enough people found your comment inflammatory or otherwise objectionable enough to hit the "flag" button.

If you have a link to the flagged comment, I can probably help you understand why HN users would have flagged it. This comment is getting downvotes because complaining about downvotes and flags always does.

What's objectional or inflammatory about my opinion here: https://news.ycombinator.com/item?id=36800745

It doesn’t show as flagged for me. Time heals all wounds, if your comment is not objectionable it will usually be vouched for eventually. Which is one of the reasons it’s a rule here that you don’t complain about voting. Such comments also rarely age like wine :)

Well it was flagged in the beginning, it's not like I imagined it.

IMHO people should be allowed to complain otherwise how can we spot deficiencies and injustices and improve?

You can complain, you'll just get a small karma hit for it. It's inevitable because it's off topic, but karma on HN is more or less meaningless anyway.

It's usually brigading by other Apple fanboys. Their master can do no evil. You could see this alot during the local device scanning controversy, but anytime you try to point out obvious facts (like Apple building the largest Ad empire for example, while virtue signaling about Meta's ads on their platform) you get downvoted and flagged.
