You don't need an ad for every fucking vid you watch.
You you would think so wouldn't you?
Let me clue you in on how youtube works, not just for Google but also for individual video creators, the people who make the content you enjoy watching.
Advertisements on videos are use by a great deal of youtube partners, including myself as a means of making a living. The channels which make the best videos out there in terms of production: AngryJoe for instance, TotalHalibut, OMFGCata rely on these to make a living and to pay for all the costs that come from making good videos on youtube. Even a simple walkthrough requires a lot of money spent on recording programs, rendering programs, microphones and finally a good solid PC to be able to record games at full HD at a reasonable frame rate. For those recording console footage they also need a capture device.
All of this can be pretty expensive, and of course there are living costs for anyone who is an adult trying to live on their own.
To anyone that might say: "STFU AND GET A JOB YOU LAZY FUCK" I will reply as a youtube content producer that this IS my job. I work a lot of hours every day and I don't have the luxury of taking a vacation because that always means a massive hit with views and ultimately earnings: Going away even one week to Germany made my earnings drop by half for that month.
Even someone producing Let's Plays, which is what I do, not only has to deal with challenge of commenting while recording ( which you need to do because companies do not like silent Let's Plays in general, and can easily slam you with a copyright strike ) you also have to spend a great deal of time finding the perfect recording settings for your software, sound settings, rendering settings in Vegas or Adobe.
Then you have to upload the video, with tags, description, thumbnail, annotations, playlists and so on and FINALLY you have to deal with all the users on youtube, because if you ignore your subscriber base you're not going anywhere but of course you are getting to constant spiteful comments, harassment, insults etc. If you are a very large youtube channel with tens of thousands, if not hundreds of thousands of subscribers then you deal with the kind of bullying, insulting and harassment on an even higher level then what Jennifer Hepler faced before she shut down her twitter account, but you also do it EVERY FUCKING DAY.
Even as a small channel like mine you still have to deal with this, on a much lesser scale true but it does get to you: You can't just ignore your comments section nor can you just ignore it when it occurs so often. Totalhalibut, who has 1 million subscribers said it's a lot worse then working at a call center for a company, because when people shout at you they are not angry at you, they are angry at your company that you represent. When they shout in comments on youtube they are shouting at you.
FINALLY on top of everything I've just mentioned you get in awesome situation where you find out that 30-50% of your entire viewer base is using Ad Blockers because "they are annoying to deal with it and they just feed this evil company".
To this I reply that while I am not a fan of some of Google's practices that they only get the lesser percentage from adds, most of it goes to the content producers. I understand and know very well that advertisements on youtube are annoying, which is why I hope they add an optional paid subscription like twitch which removes them if you pay a monthly fee, but considering everything a content producer has to deal with someone coming up and saying they use an Ad Blocker is like being spat in the face, this is why despite being annoyed by ads I don't use a blocker.
Ultimately what I'd ask is to show respect for someone's work if you watch his or her's videos often by disabling the Ad Blocker for their videos at least, and yes every video needs ads or it's a waste of time to record, render and upload it.
