It's likely not financially viable to have separate teams for their many products that all have similar features. Consolidating makes more sense because they can actually afford to maintain development.
Honestly, they should just roll YouTube Music into the default YouTube app, as well. And they probably will at some point. It just doesn't make sense to have these services - which are basically all the same, functionally-speaking - spread out across multiple apps.

I don't think I could disagree more. I use both and listening to music and watching videos are entirely different activities for me and I want the apps to do different things in different ways.
