A MapRoulette challenge is trying to resolve issues between the brand:wikipedia and brand:wikidata. Most of the tasks that are left are around T-Mobile in the US where there currently are two different Wikidata tags (Q327634 (T-Mobile International) and Q3511885 (T-Mobile US).
In most cases in the challenge, it is used with the Wikipedia page en:T-Mobile instead of the T-Mobile US - Wikipedia.
My suggestion here is to change all Wikidata tags for T-Mobile in the United States to Q3511885 and update the Wikipedia page to T-Mobile US (if one is already set).
This change aligns with what NSI is suggesting.
This would, in total, update the brand Wikidata tag and Wikipedia tag on less than 1000 nodes and ways (source)
and the Wikipedia tag of 400 (source)
I look forward to your input.
Looks like a good idea based on my limited knowledge of situation.
I set (as author) MapRoulette challenge as not discoverable so people will not be asked to do something that likely is bottable. It is still reachable with direct link. Will reenable it after either this bot edit is done and data is refreshed or if it turns out that doing it manually is preferable.
Thanks for spotting the situation.
I have now gone ahead and executed the updates.
