works great, since the change finally took effect today, ive been disliking every video i watch and posting this in the comments
"sorry but due to youtubes recent changes, EVERY video gets disliked, no offense, its a protest against the SHITTY change, not a sign i actually dislike your video. there is a temporary solution until youtube reverts the changes through returnyoutubedislike DOT com, an extension that returns the dislike button to its full glory."
i advise all who use this do something similar.

if possible maybe try setting up a sql database that keeps tracks of videos that get disliked, no identifible info, just the dislike info, so that if the workaround you found gets patched, you have a backup, and can switch it out if needed.
