Why is this confusing? The trade-off is between small ads mixed in with messages in the same area, or bigger ads in a separate area, not taking up vertical space. Like, it is surprising they decided to make that an option. Nobody adds options these days. But it should not be surprising that some people would prefer different options. If I had to guess, I'd assume the big ads version is the old behavior and the small one is what they are migrating to for consistency between mobile and web (or higher revenue).
