The biggest surprise to me is that they're reporting that the employees themselves are surprised. I don't personally know a single dev who would or even should be "surprised" by this given the current industry state.
This doesn't even really seem headline news worthy. Practically every large company you've ever heard of is doing exactly the same thing right now. And I know very few devs who actually hand-write basically anything right now even if its just an unspoken truth.
At my job it's essentially the same. Everyone is actively encouraged to use AI to move faster and barely anybody writes code by hand.
Note this is not me making a value judgement saying this is good or bad, its just my observation. Having very little hand-written code is quickly becoming the norm.
