Why don't you install an adblocker, which will block the ads for you?
This blocks all twitter/facebook/google/botnet widgets, other tracking elements, all ads, even those on youtube. Highly increases your privacy and browsing experience. I use these rules for so long I even forgot youtube has ads.
Any advice how I can get rid of ads on YouTube?
But a 10 minute ad for a 2 minute video? Even then i'll download the video just to spite the entire ad platform, thats insane.
