Exactly. Using Twitter as a primary source for this is dubious. Already seen a few accounts prove that they are where they say they are even though X shows them as being half way across the world.

Following occams razor, I think they released a broken feature and have taken it down since then to fix it. Which leads all these "revelations" to be based on incomplete or false data. Not to say the site isn't filled with bots and influence campaigns, it absolutely is. But basing that conclusion on this location information is foolish.
