People who unsubscribed from their once favorite YouTuber, what made you hit "unsubscribe"?

It's very rare I subscribe in the first place and if then I make sure it's someone who doesn't release videos very frequently or I turn off notifications. Who needs to subscribe when the algorithm shows videos of the channel you watch often in your feed anyway?

The reason I unsubscribed: very low quality of image and sound, unnecessarily long and boring content
