none of the reasons make sense sorry about the formating, but i've tried to cover all of them:
Joe the hacker
What if Joe stayed home the first day (did not get infected), got hold of Jane’s phone and decides to swat her for fun?
// What does that have to do with anything?
Joe, the slacker
What if Joe was not a neighbor of Jane, but one of her students, desperate to meet a deadline. Could he buy himself an extension by faking an infection?
// not really sure what this has to do with the tracing app...you can't fake an infection on the app, you have to get tested
Joe, the movie buff
What if Joe had invited Suzie to the movies and turned his phone off before entering the cinema hall?
// who the fuck turns off their phone in a movie theatre?
Joe, the deceived
Plot twist: Joe just caught the flu. Same symptons, different pathogen. Should he wait for test results (or be tested at all) before hitting the alarm?
// Again, you can only tell your app that you are infected with a key that you get after you test positive.
Joe, the unprepared
Joe is single. What if he runs out of food while quarantined? Will he sneak out, leaving his phone at home?
// not sure why he's leaving his phone at home? who does that? even if it does happen, it will be rare.
Joe, the kindergarten teacher
What if someone had the idea to reopen kindergarten, thinking the availability of Bluetooth contact tracing renders social distancing unnecessary?
// people want to open kindergartens because 'MERICA...not sure how this app will change things
Jane, the hypochondriac
What if Jane had an unrelated symptom, quarantined herself without a test and thinks, she gained immunity afterwards.
// what does this have to do with the contact tracing app?
Jane, the gym instructor
How many contacts would Jane’s phone log, if she left it in the locker room?
// I don't think most people leave their phones in the locker room. Even if they do, they will have contacts...other people that are in the gym at the same time.
John, the secret agent
Are there countries that would benefit from keeping other countries in lockdown? If so, what could be more effective than interlinking as many people as possible, then sending a fake alarm?
// ugh...sure...I guess...if they're bored? and they get a key from a doctor
101010, the software bug
Is it possible that a piece of software, especially one, that is based on a bad idea and coded in a hurry, might malfunction?
// pretty much everything around us runs on software...yes, there might be bugs, they get fixed
