> hat's really about the relationship with the user and timing of the request. The best practice is to ask user for a favour right after something good happens and they get value from your app as they will be glad that this app exists.

There’s that user hostility again! Also I’m not sure how the YouTube example is related. When a YouTuber says hit subscribe the user can take a second to do it. They don’t stop what they’re doing and get forwarded to a different website entirely.
