...Well, it's time for me to voice my opinion over this issue.
I am basically with everyone else here. If people want to comment on videos, they should. Why have a Google+ account to do so?! I, like almost everyone else, do not think this new policy is necessary AT ALL. Unfortunately, this is what happens when capitalism gets their way, which is what, almost all the time? Capitalism is the reason why many things are changed. Some changes are indeed necessary, while others, like this one, are not. Of course, it's good to see that a co-founder of the site agrees with me as well as a lot of people here. When I am at my YouTube account, I don't comment (or look at the section) much, as frankly, I don't like seeing harsh, stupid comments that often turn into arguments when confronted by others, but this time, if I happen to see an angry comment relating to this change, I can clearly see why.
Long story short, this change should have never been made in the first place, and I hope to see an adjustment on this ASAP.
