Please stop reverting if you don't participate in discussions. This is neither constructive nor do you seem to address any of the problems.
As you noticed in the referenced editorial discussion, all participating editors agree that this shouldn't be added.
What discussion would that be? I see a single discussion, Talk:Q25796498, where you stand totally alone, as seems to be your pattern. Point me to a discussion where anyone agrees with you.
What?! First, is Lucas Werkmeister (WMDE) not an editor? Because he seems to disagree with you too. Second, you know that's not even close to how this works. Where there is explicit disagreement, you need an affirmative consensus, not just what you consider a draw, to change status quo. But again, you know these things. You just seem not to care. Maybe you think your experience level here means you can act with impugnity. I promise this is not the case.
WMDE employees don't participate in editorial discussions. I think they are even explicitly barred from doing so. Maybe you want to ask Lydia about it.
Maybe you want to show me where that's stated, if you expect me to trust you on it (hint, I don't). Regardless, you have my explicit disagreement with the change. That alone obligates you to get a real consensus.
I am interested in what Lydia has to say, but note well my last comment. My opposition is explicit, and I'm certainly not barred from commenting. You still need consensus, and you still don't have it.
No, you are free to oppose and to revert. It can be done without having a reason or giving an explanation.
Editorial decisions are with the editors, yes. I suggest getting a neutral third party to have a look at your dispute.
