YouTube doesn't have to defend itself. Read this thread and understand how shitty/entitled it's users are.

Then these adult children go an complain there are no competitors. No shit, you scoff at subscriptions and wear your ad-block like a badge of honor. Who the hell would invest in making a platform for non-paying users?

Strangely enough, I do feel entitled to download data from YouTube using standard protocols on a standard port. It's not like I'm breaking in or anything.
