When we had the downvote button on Youtube we were able to filter the crud from the creme in comment threads and have real discussions. Groups of trolls are now able to upvote their comments to the top of the threads and anger / annoy large groups of people and now we have little to no way of getting rid of them (the report button doesn't even seem to work most of the time anymore). Its been doing the exact opposite of what they said it was to do for everyone (preventing hateful comments and encouraging positive discussion). It is very clear just how much damage these changes have caused and now they are trying to remove the downvote button in the product forums / Groups services. As a result of these changes, many popular youtubers such as TotalBuscuit, iJustine, OfficialNerdCubed, and many others (https://www.reddit.com/r/youtube/comments/1qbg5i/list_of_wellknown_youtubers_who_have_publicly/) have been forced to disable their comment sections because of harrasment, spam, trolling, etc. It is more than clear that this isn't working in the favor of anyone at all.
