I don't know how much it costs to run or how ads fully function on the service, but we do have Odysee. I have yet to have seen a single ad from my collection in the app outside of creators whose vid that's also up on yt having a sponsored segment.

Edit:

Just booted up the app for the first time in a while and they have some minor things. Noticed a little bar at the top with a list of channels and scrolled down to find a featured section.
