This is coming from Glenn Greenwald, a known Putin shill, so all this could mean is the efforts to maintain truth on Wikipedia, since Ruzzia and her allies worldwide (including the American Republican party, or at least the 'MAGA' portion) constantly seek to obfuscate the truth and alter articles critical of them, their positions, their narratives.

Now I'm not saying there isn't a shred of truth, there usually is with shills like Greenwald, so I'm sure the US and their allies are actively involved in doing something similar, but nobody lies like the current Ruzzian regime and their allies, their people are so misinformed and propagandized that they wouldn't know the truth if it smacked them over the head.
