Screenshot of Change.org page has 177,816 signatories to protest
Comments on YouTube used to have a lot of opinions that lacked objectivity. Therefore, Google believes that the application of Google+ comment system will be necessary to change the quality of YouTube viewers' opinions. But in a week since the new comment system was released, the problem still has not been resolved. In fact, YouTube's non-video comments continue to appear more and more, this is because Google+ allows users to submit ad links, unlimited characters and many other extended features.
Hopefully, with nearly 200,000 signatories to the protest on Change.org, Google will change its decision.
