I noticed this, too. I think it speaks less of spell checkers and more about Time's ability to do copy-editing.
If I submitted a piece to a major outlet such as this, I would do so in full faith that they would assign at least one person to read through it and copy-edit it before publication. Apparently, Time is not a sufficiently reputable institution of journalism to believe in doing this, or at least is unwilling to spend enough money to have it done by competent people.
EDIT: As for Janet's credibility, I can speak to it personally, having spent a year with her working down the hall from my office. Probably the coolest stuff she's done relates to how decisions are made in big teams of scientists (she studied the sociology of scientists running some Mars rover missions: http://janet.vertesi.com/projects/social-life-spacecraft).
