How to use youtube without supporting google:

1. Newpipe- Android app that removes ads, has background play and you can download videos.

2. invidious- alternative front end for youtube that does the same things as newpipe. But you may have to change instances alot becaues YT keeps blocking them.

3. Libretube- Android app using an invidious backend with a nice UI. Not as stable as newpipe though.

4. Freetube- Desktop app that saves all your sub data locally, watch ad-free and skip sponsors
