They are certainly one of the most annoying classes of ads, which is why I was exceptionally annoyed when Amazon put one before a Prime video I was watching a few days ago.
Granted it was for an Amazon product, but any sort of ad in a paid service is _extremely_ annoying.
So the cinema has to somehow make money – and that is with ads and food.
I've started using a similar strategy on YouTube in order to selectively "protest" against bad ads. Whenever I stumble upon a long unskippable ad or a short very aggressive ad (loud and/or offensive), I mute the video and start reading comments for a while, or I alt+tab to a different video, etc. Sometimes I leave the page if the video (or uploader) is not worth the hassle.
In my mind this can lead to 3 different scenarios:
* Google notices this behavior and decides to enforce heavier regulation on ads (they already killed >30s unskippable ads this year).
* Google notices this behavior and tries to fight it (e.g. by pausing the ad if the volume is not low enough, the Spotify way). In the browser this leads to an arms race that Google can't win. In the worst case I would go back to avoiding all advertising using adblock and/or alternative financing if available (YouTube RED, patreon, etc.)
* Google doesn't react, bad ads lose so much value that most uploaders stop using them. They don't want to alienate their viewers for so little benefit.
We need many people to apply this strategy for this to work. However in the short term content creators still get paid, and I get the personal satisfaction of screwing over bad advertisers.
The funny thing is that they also pause videos when changing app/tab (not only ads), because background playback is a YouTube RED "feature". I would understand if YouTube RED was available in more than 5 countries. They have been artificially depriving their users of a basic feature for years and for nothing.
In the meantime I simply avoid watching long YouTube videos on my phone, and use NewPipe to listen to podcasts hosted on youtube (which means no ad revenue...).
Ah yes, the realization that all the spy-economy-supported content provides vanishingly little value to your life, and that if they managed to actually lock things down so you couldn't block ads it'd harm you not at all to simply stop looking at their stuff. A liberating state of mind.
If ad-blocker-blocking gets too good, I could ditch it at an infinitesimal cost to my quality of life. My alternatives are many and could last a few lifetimes even if no new content of any kind were produced at all. News, even? A news habit is of about as much practical value as a soap opera habit. I could drop this stuff like that. No problem. Go ahead and somehow permanently break my adblocker or wall off a large part of the web behind custom protocols and DRM. Bye bye.
[EDIT] the "realization" I meant in my earlier post was that, on examination, one may find that desire to watch/hear/read most ad-supported media is so low that not only is it not a need, it's barely even a want.
Also, ads in YouTube — the content creator enables that so they can get paid.
Personal anecdote time.
Preroll ads are the main force for me behind installing the adblocker. I just can not stand something that manipulates my flow. I call it televication of the Internet. It is unbearable.
If for some reason I am not able to block them then I just do not watch them and I am not listening to them (I look elsewhere, say a lalala mantra in your mind).
I also taught my family to do so.
So advertisers actually loose in the long term.
