This is hardly a shock. All the other media peers, who have less resources to absorb streaming losses (save Comcast), have been laying off people in the last few months and it was only a matter of time till Disney caught up. The hiring freeze is also unsurprising given how massive the headcount is (only Comcast has comparable numbers but the vast majority of them work on the cable side, which is Comcast's bread and butter anyway).
Hopefully the bloodbath isn't as horrendous as WBD's downward spiral, and their only good decision they've made thus far is hiring Gunn and Safran to mange DC's media projects.
