I have no issues with people not wanting to use the app or using a burner to do so if they leave proper contact details. If you're Jimmy Lai, it seems sensible. For 98% of the population, it seems paranoid but whatever floats people's boat. What do I care if the government knows I've been to a particular restaurant or building? I have issues with people trying to game the system, lying and hiding to avoid being found in case of necessary testing. The excuse that the government might all of a sudden round up everyone that's been in a particular location and send them to quarantine is again somewhat paranoid though they did put a bunch of kids and teachers doing exams in a hall which seemed a bit over the top. The more likely and sensible path is that people be informed/tracked to be tested. I accept the risk of being quarantined because the flip side of hiding myself while being positive and infecting/sending potentially dozens of others into quarantine/hospital as one moron did is simply just too selfish, if anyone was that irresponsible, I would fire/ditch them in a nanosecond. Ironically the reason why harder quarantine and stricter tracing is necessary is illustrated here by the amount of people that are quite happy to flout rules because they are more concerned about themselves than the risk to others. I certainly don't disagree that there are flaws and inconsistencies in the government's approach but if they are trying ways to open up businesses more quickly and being more selective in targeted closures/testing, I'm all for that instead of everything being shutdown.
