I agree tests are useful, however the advice was not specific enough. The WHO should have specified how many tests are needed for various outcomes, offered early modeling, and facilitated information exchange to improve those models. Instead they simply played politics and offered very generalized and non-specific advice which overwhelmingly downplayed the risk. Maybe a country has 1000 tests on hand, they test that first 1k people and can say they followed the WHO's advice. That's all that was possible given their immediate stock.
