I was browsing for a solution to download files from a link into Google Drive and came across this answer, which is a community wiki, and has at the bottom of it the text

I had previously thought that the purpose of downvoting was to indicate that an answer does not work. However, this is my first time I consciously remember considering downvoting a community wiki, so I figured the rules might be different, so I should ask here.
Do community wikis have different conditions as to when one should downvote?
