This article is full of hyperbole.
But to address the central point, people are being quarantined for 14 days (which isn’t a true quarantine, which is 40 days) because they are coming from a place where corona virus is on the loose. Doing this for 14 days is surely inconvenient for them, but it isn’t like they are in a cold, wet cell with a cement floor, being beaten every few hours and fed a tiny bit of worm-infested food. No, I’m sure that they are being treated quite well - and the purpose is to protect the rest of us, including the authors of hyperbolic blog articles.
Where did you get the idea that a true quarantine Is 40 days.?
