I find YouTube ads to be just weird and annoying.
i) I get gambling ads. This is a sleazy destructive industry and people should have to opt-in to receive ads for gambling products. (Ditto alcohol).
ii) I will queue up some obviously children's content for my son but get an adult's ad (eg ads for violent film) before that. This is fuckig stupid and it's disappointing that Google gets this wrong.
iii) I'll go to watch a 30 minute video but get a 5 minute ad. (Or maybe 3 minutes?) I should start making a list of the company names that do it.
iv) a lot of the ads are just terrible
Google really needs to implement some controls so people can avoid alcohol and gambling ads.
