Is there a reason why YouTube can’t implement something similar to Twitch subscriptions and Patreon backing to YouTube? I see that an increasing number of smaller YouTubers are relying on Patreon to supplement their income because their YouTube revenue has been cut significant.

A smaller number of dedicated fans are willing to pay more money directly to the creators that they enjoy and connect with.

How does this affect their relationship with advertisers more than YouTube Red, if at all?
