No they don't have incentive to cultivate developer goodwill. They are monetizing replacing developers everywhere. That is the trillion-dollar valuation. They have the opposite incentive.
The only thing that could prevent this is lack of ability to execute, like how Uber wanted to replace drivers with FSD vehicles.
Even if they believe that their systems will eventually tank employment and replace developers rather than augment meant, the fate of Astral doesn't matter at all in that scenario because a) nobody has a job, and b) you can build your own uv replacement for $20.
Those two are pathological liars, so what they write about means very, very little.
