With their resources and the nature of the service, they could easily win the cat-and-mouse game against ad-blocker devs if they wanted to.
The reason they don't, is because they actually want to keep those "entitled people" on their platform, in order to avoid giving competing platforms an opening to grow their own communities. They know there is a substantial part of their userbase who would simply not use their service if they had to either pay or endure the vanilla experience.
Regarding ads: Showing ads like "Girl Mobile Video Talk" with description "Girl Mobile Number Live Video Call" with "Install Link" in a youtube ads is unacceptable. And the worst thing is you cannot even turn off that ads without being turning on ads personalization.
Regarding Money: 10$ may be a cup of coffee for you but in other side of world people are earning 200$ of salary so they just can't afford it. So many people don't have privilege like average Americans have?
Regarding supporting creators. Sure ads pay creator but showing ads every 10minute , beginning of video and end of video is total BS. And even creator are already using their own ads like "This video is sponsored by Brilliant.org" so I don't mind blocking ads.
