the “open source hackers” are always going to win this one, for a simple reason. if the data of the youtube video is handed to a user at any point, then the information it contains can be scrubbed and cleaned of ads. no exceptions.
if google somehow solves all ad-blocking techniques within browser, then new plugins will be developed on the operating system side to put a black square of pixels and selectively mute audio over the advert each time. if they solve that too? then people will hack the display signal going out at the graphics card level so that it is cleaned before it hits the monitor. if they beat that using some stupid encryption trick? well, then people will develop usb plugin tools that physically plug into the monitors at the display end, that artificially add the black boxes and audio mutes at the monitor display side.
if they beat that? someone, someone will jerry rig a literal black square of paper on some servos and wires, and physical audio switch to do the same thing, an actual, physical advert blocker. i’m sure once someone works that out, a mass produced version would be quite popular as a monitor attachment (in a timeline that gets so fucked that we would need this).
if that doesn’t work? like, google starts coding malware to seek and destroy physical adblockers? then close your eyes and mute your headphones for 30 seconds, lol. the only way google is solving that one is with hitsquads and armed drones to make viewers RESUME VIEWING
as long as a youtube video is available to access without restriction, then google cannot dictate how the consumer experiences that video. google cannot win this.
