Your choice and everyone has one despite ads or not and I know you are very down on Google and can't say in many of the cases and how they do things I can't blame you. I feel the same with privacy issues but it is not going to keep me from watching You Tube videos that I enjoy!
It's a free app and a great app. For a few advertisements that are thrown in to enjoy what many consider the best app on the planet. If you choose to pay a few bucks you can always buy a youtube replacement app and you want have to watch any of those pesty adverts. I have both, the Google YouTube app and also a paid version. I couldn't use my 5S without Google Apps, between G-Mail, G-Voice, YouTube, G-Drive, G-Search + rescent update is spectacular, use it instead of Siri, Google Maps, Chrome Browser. Holy ****, just realized my iPhone 5S is a (Google/iPhone 5S) I'm just counting the days when I can jail break this thing. Then I can do some hacking.
