The coverage of the Hong Kong protests is very partisan. So much that is hard from an outsider to gauge exactly what is going. (Compare it to eg. India / Kashmir or the protests in France.)

However what is obvious is that the HK government has a number of measures to do before it resorts to complete censorship or invites the army to take over. For example here in Denmark wearing masks in a public demonstration has been against the law for the past 10 years. Meaning that the police can arrest you immediately if you wear a mask and also (probably) dissolve the demonstration.
