Sorry Google/Youtube, but you're fighting a battle you cannot possibly win. Everyone I know will always block ads no matter what Google does, period. If there comes a time when they can't block Google's ads then they will simply move to a different platform.
Google now thinks that Youtube is in a position where they can get away with this, because they believe Youtube is a must have for everyone, but they're sorely mistaken. If I can never use Youtube again because I refuse to watch their ads then I'm 100% fine with that.
PS. - I absolutely hate ads and will not watch ads on any platform (internet, TV, etc.) I know people will say we get great content because of ad support and all that. I DO NO CARE. I will not watch ads no matter what. I don't care if every company that relies on ads goes out of business. Good riddance. Find another way to generate revenue where you don't annoy your own users. I'm old enough to remember a time when 30 minute TV shows were actually ~24 minutes long with ~6 minutes of ads. Now most of them are 20-21 minutes long with 9-10 minutes of ads. That's almost one third of your time wasted on ads!
