I'd still look at YouTube as an acquisition done right. How long has it taken for Google to introduce something that you don't love re: YouTube? At this point, all Google decisions related to YouTube have to be considered independent of the acquisition.
I was mainly referring to the commenter who said the G+ issues being his first problem with the YouTube acquisition. If that was your first major issue, I'd call the acquisition a success. Also, how much of content ID was YouTube covering it's bases legally with the DCMA? I guess, are there easier ways they could have been compliant while being less irritating to users like yourself? I honestly don't know.
