Well that's a great incentive for clickbait content - cause now it won't matter if you can keep people watching after you've reeled them in.
You'd think this would be against YouTube's own best interest, considering they want to keep you watching, and people don't often like watching that kind of clickbait-farm slop...
Or maybe I and the people I know are in the minority, and a lot of people just watch it whether they like it or not, which would be disappointing to hear.
