"as the primary means of control of the virus". The WHO has consistently said that the primary methods of controlling the virus are tracking, tracing, handwashing, mask wearing etc. so that lockdowns aren't necessary. Lockdowns have been necessary when there are too many cases to track and trace so they don't know where the chains of contagion are happening. It is effectively a mass quarantine measure. This is part of the problem when everything is viewed in some sort of binary situation. How is this any changing of their advice? In the statement you quoted, the measures they're suggesting as the best way to suppress and stop transmission isn't the lockdown.
