It about device detection and privacy. Websites in the EU aren't allowed to scan your hardware or software without your permission, to protect the users privacy. Adblockers fall under this.
If thats how it works, they could very easily just check if the ad ever got loaded and refuse to serve you content until it does. Going after the way they prevent people from abusing their services doesn't stop them from preventing them - it just gives them a new hurdle and that's not a very big one.
Well many adblockers can be clever enough to load the asset, but then just drop it. As in yeah the ad image got downloaded to browser, but then the page content got edited to drop the display of the add or turn it to not shown asset in css.
This is age old battle. Site owners go you must do X or no media. However then ad blocker just goes "sure we do that, but then we just ghost the ad to the user".
Some script needs to be loaded, that would display the ad? All the parts of the script get executed and.... then CSS intervention just ghosts the ad that should be playing and so on.
Since the browser and extension are in ultimate control. As said the actual add video might be technically "playing" in the background going through motions, but it's a no show, no audio player.... ergo in practice the ad was blocked, while technically completely executed.
Hence why they want to scan for the software, since only way they can be sure ad will be shown is by verifying a known adhering to showing the ad software stack.
Well EU says that is not allowed, because privacy. Ergo the adblocker prevention is playing a losing battle. Whatever they do on the "make sure ad is shown" side, adblocker maker will just implement counter move.
Your comment makes me think of Googles new DRM protocol, and then about Ken Thompsons compiler hack, combined with most DRM get hacked eventually.
This gives me hope that even if Googles DRM becomes standard, it will be hacked and YouTube thinks it's showing ads on a unmodified signed page, but I am not seeing any ads.
