I recently discovered a slight mitigation on the iPad re Youtube ads:

If you open a Youtube URL and the preview image looks like it's not the actual video but an ad -- wait. Wait for approximately the length of the ad, and the preview will switch to the actual video's preview (or the next ad, in which case, wait again) and you can then play the video.

(I think this is probably not intended behavior and I hope I'm not getting this "fixed" by posting this here :/)

/edit: I do this is on "Firefox" for iOS, though it probably shouldn't matter.
