In general, it doesn’t actually seem to think about reasons why China would continue open-sourcing things. The supplementary materials don’t really motivate the closure of the algorithms; and I can’t recall anything in the narrative that asks why China is open sourcing things right now. But if you don’t know why it’s doing what it’s doing now, how can you tell why it’s doing what it’s doing in the future?
Agree with (b1) and (b2) in this section and some parts of (b3). Also, open sourcing might be very good for hiring?
But, worth noting there are a bunch of reasons not to open source other than just avoiding accelerating the US. (Maybe: worries about general societal upheaval in China, CBRN terrorism concerns real or not, general desire for more state control.)
