Should the BBC be privatised?

... on YouTube. It has adverts ...

FYI I only occasionally watch a youtube video but ad blockers (reasonable ones) will block all youtube ads. When I do watch anything on youtube I never get any ads.

So if you don't want the ads on youtube just get a good ad blocker.

I make a distinction between a trailer and an advertisement which you refuse to recognise.

I don't refuse to recognise it. It may be a relevant distinction for you but to me it's all unwanted irrelevant pushing something

Perhaps you are not a parent. I suspect that for many parents the distinction is obvious and significant.
Trailers for upcoming programmes do not encourage children to want things and pester for them to be bought.
Advertising is designed to do exactly that.
