Low accuracy, intrusiveness and potential health risks of the tests aside, I would always refuse on principle to get a wuflu test, purely because any info from the test would be used to attack my interests. To harm where I live and my friends and neighbours, to impose lockdowns, mask mandates, restrictions on businesses and travel. Deny people this info, and no harm can happen.

If governments want to position themselves as an enemy and order billions of dollars in harm done against innocent people, then denial of info to ones enemy is the first law of warfare.
