It's impossible to keep track of the Chinese government, so it wouldn't really surprise me if this was indeed the case. I have always found these two exchanges to be somewhat different from the rest, and this might become even more clear when the government aims its focus at these specific exchanges. China doesn't really care what path it goes through, it just wants to make sure it ends up with as much control as possible, which is understandable to a certain extent. It must be frightening for governments to see Bitcoin and crypto in general only grow in size/usage. One way or another, basically every government will at some point take certain measures to gain at least some control.
