==Bad copyediting IP==
This is the "bad copyediting IP", whose changes to article text over-simplify it unnecessarily, leading to more pedestrian wording, such as might be written by a high school student; also ungrammatical writing.  See [[User:Beyond My Ken/Bad copyediting IP]]. ~~~~

Examples (list started 5/22/2023):

• changed section header "History since publication" to "History since the publication of it" [1]
• changed "countries sanctioned by the communist authorities" to "countries which was sanctioned by the communist authorities"[2]
