That's where I disagree. YouTube got this big because it's been free for so long, it practically squeezed out all of its competitors. Now that it no longer have competitors, YouTube started charging subscription, even raising the price now.
Also, you can't exactly compare YouTube subscription with Spotify subscription, because Spotify got its content mostly by paying records companies. YouTube on the other hand got majority of its contents for free from their users, just like Reddit and Twitter. Even if you subscribe to YouTube premium, the majority of those video owners will never get any money from YouTube.
YouTube Music is more comparable to Spotify, but why bundle it with YouTube premium and raised the subscription price instead of offering it as a separate product and keep the base YouTube subscription cheap so it'll make more sense for most people.
Looks like they won't publish a timelapse video after it's all over like last year.
