On purpose? Not much.
The bigger concern would be when a criticism of China would be an important facet of a topic that would be covered, and omitting that would detract from the accuracy and comprehensiveness of the content.
Imagine if video hosting platforms couldn't call out any of the stuff Trump does as wrong or incompetent. So so many topics would have to be ignored entirely to avoid offending the administration. Currently China criticism is a little less critical in the moment by comparison, but things shift over time.
Private companies are allowed to decline to host at their will. USA nor EU mandate that a platform must host content they don't want to.
In practice, it's possible that China companies operating outside of China won't implement the same restrictions that they do within China. Whatever the Chinese government thinks the importance of maintaining censorship within the borders, it seems probable that the government and companies will be more pragmatic about realities in other nations.
