The Terms of Service of Google map products explicitly forbid you to use their resources in competing products, which OpenStreetMap happens to be.
As your daily experience trumps everything, please refer to that, and don't reference Google (though here I interpret it as a confirmation of your on-the-ground observations).
In short, no worries.

actually, no, this changeset is a node, and the building is MoAra B..... which i should have noted earlier.
Again, I ask without checking the area history, what do you want to see here?

it is already on the map for me, as a square building and superimposed, your name Mora B....
Is that enough, or are you expecting to see more?
in any case, you may have cached older tiles, and it can take some minutes, hours, or days to appear at every zoom level.

This changeset has been reverted fully or in part by changeset/62196331 where the changeset comment is: revert a maps.me wide-reaching changeset rather than check every node - bakery in water? names are mostly danish descriptions and most categories are nowhere near the description. mostly personal bookmarks that should never have made it public.

is it already ... no, it has been all along...

I just found it interesting when looking at a resolved note advising it has been changed, that a web search turned up the previous version more than the new name -- and the non-space variant was in use by the stadium's own website and their other social-media.
way/25312625/history shows that the present version was used in the past history of the item.
As I see both variants in use on a number of different sites, and your first-hand experience contradicts what their own site puts forward, but there is no content difference between the two, my suggestion is to add the other name with documented usage to the alt_name field, so that the stadium is found regardless of which name variant is searched.
.
I do not know which is more correct or preferred, or if the compound AmericanAirlines merely resembles the logo typography, as i use a text-only browser for these things. Unless convinced otherwise (which is easy), I would tend to defer to the official site in this case as authoritative how they write their own name.
.
Also, if I read the referred history correctly, there used to be a name:en= entry as well as name, which is a good idea to preserve here with contents matching name= , as the latter gives no clue as to which language it is, and several applications will treat a specific language entry as special.

What is your source for changing the name entry from AmericanAirlines and adding a space between?

while the two other names of the year-old edit war do not return any useful results, unlike Leo Long Track which is quickly verified, it does seem The Quad in lowercase sees frequent use.
Most effective search terms:
"the quad" lahs
details: no-cookies text search to https://www.google.co.uk/ served by I believe the Düsseldorf data centre, but should be applicable worldwide.

do the newly-added nodes like node/5861312809
that survived the revert correspond to anything like an entrance?
i am reviewing everything else now.

This changeset has been reverted fully or in part by changeset/62056061 where the changeset comment is: formal revert to restore amenity=school to a high school node. proper changeset might help or i need sleep.

This changeset has been reverted fully or in part by changeset/62056040 where the changeset comment is: formal revert to restore amenity=school to a high school node

and were you really meaning to do anything in norway, and if so, what, and how does it relate to the school library you added?

no worries, there are at least two other mappers reviewing what remains of the conflicts, so that by the time i got around to them with my painfully crippled equipment, most had already been attended to.
after i wake up (if i sleep :-/) i may make another pass over the edit wars and make certain i am satisfied with my reverts and undo any collateral damage.
a big thanks to all who have helped out.

has been deleted

manually deleted

name is plausible, restored

reverted to v2 but The Quad was deleted after a long and colourful history - does anyone know more about it, i ask forgetting there are search engines...
