I don't have the medical knowledge to make an informed statement on if making her stay in a quarantine facility was right or wrong. However, refusing to "stay at home for 21 days and we'll pay you to do it"? Sorry, at this point she's just an ass who wants fifteen minutes.
Her boyfriend said in an interview that they aren't seeking to push any limits.
What a dweeb. She's not doing anything BUT push the limits. That town in Maine is a small, close-knit community of only 4000 people. And it's not part of a larger "greater metropolitan area," unless trees count as metropolitan. She's receiving death threats from her neighbors, which is very unMaine-like. That should be her first clue.
But ... "there are none so blind as those who will not see." Clues are wasted on the clueless.
