And, likewise, Youtube is free to send the bytes to only the people they want. If they don't want to serve video data to people who use adblocks, it's their right.
You are then free to try to work around it, the same way Youtube is trying to work around your adblocker.
I'd agree with that, although that doesn't make both activities equivalent either.
Google is being increasingly obnoxious and user-hostile in an effort to get people to pay Google money to stop harassing them and wasting their time by delaying and interrupting the free content they requested with repeated attempts at manipulation, while the people who block ads are just trying to avoid Google's unwanted (and at times harmful) behavior.
Google's bandwidth and storage for the valuable content the public produces and provides to Google for free are more than paid for by the personal data they take from us and use against us at every opportunity. Google has the trillions to prove it. Some subset of youtube viewers depriving them of just one opportunity to exploit our personal information isn't going to hurt them one bit.
