Dumping is such a loaded term. This is investor-backed scaling to capture market share, standard VC playbook.
It's state-backed, or at least state-directed, scaling to capture market share, standard CCP playbook since the 80s.
Whether dumping is a loaded term of not is irrelevant; it's a specific term of art in economics and policy, it fits with the context of past national actions there, and fits what's currently happening here perfectly. They put money into these models, then give them away for nothing (below cost).
It will never stop being funny to me that China does the exact same shit American corps have been doing since the 70's but because it's scary China it's suddenly a problem.
American startups flood markets with below-cost loss-leader products explicitly to kill competition and create network effects, and then jack the prices just as high, if not higher, for the service in question after the fact, oftentimes while making it so those providing the service earn even less money than they did before. Commentators: "Free market great"
China does the exact same thing: "Communists wanna kill the West"
There's a difference between state sponsored and private dumping.
