Without talking about the resources it would require, youtube could totally only serve the ad until it has been “watched”. And no amount of sponsor block or similar software would help. These software only work because youtube allow you to navigate the video. If they decide that you have to fully download a 30s ad video, and that you can’t ask for the video for the first 30s, then you wouldn’t be able to do anything (or at the very max, just hide the ad and wait 30s on a blank screen).

Is there a deeper meaning than just that they are all tools to break the ground? I have a feeling there’s a deeper joke but I fail to get it. (non native speaker here)
