Why is YouTube forcing full unskippable ads before music videos now?

It used to be if you wanted to hear a music video you could choose "skip" to skip any ads and get right to the video. Now you have to listen to a full ad (the one I just saw was the cure for poop clogging your colon πŸ’©) before the music video starts. What's with that? Anyone see this happening?
