My problems:

• Ads not for kids in kids videos.
• Very long “ads”. Let’s say, 1 hour? I know that there are longer ads, but, well, if you think that an hour ad is not a problem, well…
• Ads everywhere. In the video, in the recommendations bar, in the main page.
• Ads INSIDE the video. I know this is not about a youtube thing, but I really hate being in middle of some video an then the guy starts talking about Brave or something.
• The pourly implementation of ads in middle video. On TV you were able to tell when and how the ads would came and felt natural because your content wasn’t cut out of nowhere.

Taking it from the last point: that’s why I love Pluto.tv. I can be watching my, whatever, and then I know that ads are coming, because uses the same timing as regular TV, so I can use that time of ads to just ignore them and get on my phone or do something else, like old TV times. Not in middle of my video that it’s gonna last 5 minutes, damn.
