thought about role of PBOC

Today there was a statement at cointelegraph.com "There is a view among some experts that the Chinese central bank’s actions are benign and are motivated solely as a reasonable and responsible regulator."
What if PBOC is not the "bad guy" as many think, who from time to time makes the BTC chart nosedive by sudden rulings or requests.
What if instead PBOC just now and then releases restricions, new AML rulings, and so forth just in order that the price doesn´t get overheated? So that by their actions tiny holes are punched to prevent creating a bigger bubble? At least it looks like that. In that case shouldn´t we be happy on the long run about their constant interventions?
What do you think? Is that plausible?
