If you look at releasing "everything" from the perspective of a quant and purely so, then the objective to dominate a metric relevant to the quant is obviously the motive. But it's impossible to prove and a very strong assumption with little to no data. If DeepSeek's parent company traded on the data and release of DeepSeek with quant models that target affected firms with shorts before release, then that's a whole new level of WOW and honestly great funds do that. But this is a too big and bold of a move to underpin motive.

But believing a man could achieve such a feat alone is inspiring to be frank.
