Isn't it against Google's terms and conditions to run such an app that plays YouTube videos without playing the ads too? I remember reading about that.
Considering that Google charges subscription for this features, it's not only against ToS, but also unethical IMO. It's one thing to hate a company and refuse to use their products and a whole nother thing to promote products that sidestep features the service asks money for.
With that I have almost exhausted the list of ads that Google thought has been relevant for me since I started dating my wife well over a decade ago.
Why they cannot show ads for family holidays, programming conferences, local stores etc I don't know but if I had to guess I'd say they could need some diversity on their teams ;-). (Adding a few married parents with stable marriages and small children should do the trick, but I am not interested and haven't been for a couple of years, I find Google close to disgusting sometimes and whatever technical edge it has has disappeared to the degree that I'm positively surprised to just see sane results like they used to be in 2007.)
