No, they're not talking about clawed frogs (family Pipidae), which have ordinary non-retractable, keratin claws. These Artholeptidae frogs have claws made of sharpened bone that pierce through the skin, something really unprecedented.
So yeah,
African frog with claws != African clawed frog
Couldn't this be preserved by viewing these not as publishers, but as mere "content aggregators" of (open access) content? I'm familiar with one such "aggregator" service. It's called Faculty of 1000. A bunch of prominent researchers highlight important articles (especially "hidden gems" from lesser-read journals). The user pays a subscription fee to benefit from their service of separating the wheat from the chaff. It's a helpful time saver, and I imagine such services would become even more important in a decentralized, open-access system.
It surprises me that people can be so dismissive about this when they don't even know what they're talking about. Look at the abstract of the actual Nature article (http://www.nature.com/nature/journal/v448/n7154/a bs/nature05986.html). The reasoning is quite clear. Most evidence until now has pointed toward a progressive lineage, but now we have evidence of coexistence. Hence the importance of the finding. The scientists are not surprised because they thought coexistence of the species was impossible, but because it runs counter to most other evidence.
