> YouTube ads will eventually be as bad as TV ads have become.

There's no evidence of that though. Users will easily close a tab because the preroll ad is too long, because there are plenty of other immediate things on the internet. In a way that TV viewers had no choice, because the other channels are just as bad.

Yes, YouTube ads have been getting a little longer from their previous almost-nothing. But YouTube has also been extremely conservative in that direction, as they know they're walking a fine line. The idea that ads will get as bad as broadcast TV seems exceedingly unlikely.
