Definitely this. Wowhead's data are contaminated with stolen presents from last year, which couldn't contain Rotten Helper, so the droprate appears artificially low there. Wowdb wipes its data between patches, but consequently doesn't have enough data for Stolen Present yet.
Some quick math from the responses in this thread (including my own 1/3) gives 5 helpers from 115 presents, which supports something like a 3-5% droprate. Lil Bling is a 2% droprate, and we already saw how fast Lil Bling's value plummeted within just a couple weeks of becoming available.
