sien: If you think this decision was wrong you can try to bring it up again, and point out the discussion in Wikiprojects or other community pages where a larger number of Wikipedia editors will see it. If you could only get 3–4 people interested enough to discuss and nobody could come up with an acceptable compromise, that’s not really the fault of the process. If you think these particular editors did something improper, you can escalate to further community processes designed for dealing with various abuses.

The nature of any large project is that people will disagree and not everyone will get precisely what they want.

Yes. This is true. But honestly, while it still midly annoys me it just doesn't seem worth the effort.

What was interesting is just how unobjectionable this addition is and how hard it was to go through all the processes.

I've added stats in a few wikipedia articles which have all gone in just fine. With this one part of it was OMG, really, you can just object and object and keep something out if you're determined enough.

From the other side, editor X is doing their best to present a neutral and accurate view of a topic, and editor Y (who is a random stranger to them) keeps trying to add survey data which editor X believes to be methodologically unsound to the point of irrelevance.

(Disclaimer: I didn’t investigate this carefully enough to have a well formed opinion about the outcome.)
