Anthropic and OpenAI took your data, trained their model, and tell you "we are not going to tell you anything how we trained our models, we are not giving your the weights our models, you will have to pay us to access the model trained from your data".

they took your rights and your data.

Chinese labs took your data, trained their model, and tell you "this paper details how our models are trained using your data, here is the final weights of our model trained from your data, feel free to use it for what you want, it is your model trained on your data".

they converted your data, everything is still in your hand under your control.

you couldn't see the difference?

Your specific question can actually be translated as -

1. why people don't stop Chinese labs so US monopoly can be maintained?

2. why people don't stop Chinese labs providing free models to those who would otherwise never be able to afford the same $200 USD/month Anthropic and OpenAI subscriptions.

3. why people don't complain Chinese labs publishing those trillion dollar secret ideas on model training.

well, because most people are not dickhead I guess?
