Like it or not, the whole way "free" services on the internet work with ad-blocking, and always have, is that the people blocking ads are taking advantage of technological measures to avoid them, so that the actual cost of serving content is paid (by ad-viewing time) by all the suckers who don't know how to block ads, or don't want to for some reason. It's basically like that with sponsor segments, though here I think it's more like a television or newspaper ad: the sponsor is simply hoping enough people will watch the segment and go buy their stuff (since it's personally recommended by the content creator!!) to make their sponsorship investment worthwhile.
