Yuri is getting tired of ads on YouTube. They are now running ads all the time. It's very annoying. Leo says Google wants to push viewers towards their YouTube Premium service in order to get a monthly subscription rate. So that may be why all of a sudden, everyone is getting more and more ads during a stream. Leo says an ad blocker can help. But you can also block ads on the DNS level with NextDNS.
On Android, Firefox Focus is a good blocker for ads that can filter out things on your apps.
