Personally, I don't object to ads being displayed on Youtube, I just don't pay them any attention. Something has to fund the service and infrastructure required to host Youtube, and that's either going to be advertising or subscription revenues or a combination of both. Since i'm not prepared to pay for a subscription, I can hardly complain that I am shown ads.
In the early 00's, I had a discussion with an advertising executive regarding the skipping of adverts on broadcast TV. I'd been a PVR user since the late 90's (a Phillips TiVo) and informed her that I hadn't watched an advert for years - I always skipped past them. She was absolutely shocked by this and got quite upset. Apparently I was guilty of breaching some kind of un-written contract between myself and the broadcaster. She claimed that I was contractually obliged to watch the adverts whilst watching TV and that not watching the adverts was somehow stealing the TV!
This wasn't the first time I'd witnessed someone's reaction when their worldview was shattered by a new piece of technology and I'm sure it won't be the last.
