You will get these sponsorships:
If you leave Freedom! you will lose access to them and you won't be able to upload new videos using their licensed music.
These 40% would stay with you BUT with AdSense (aka YPP) you wouldn't get paid without earning 100$. About the services, you get access to some sponsorships, music catalogues and some other services like epoxy.
When partnering with Freedom, you will get 60% of what is being displayed in your YouTube Dashboard. When looking at the freedom dashboard you'll see the exact amount of money you'll get.
Hey,
YouTube does decrease your quality by downscaling the videos in order not to take up as much space. The video quality mostly gets better when all CID checks have passed through.
