Yep, those articles have been discredited.

The labor market has been tight! There was a wave of job changes back a year ago -- but to be clear, those were not people who were leaving the labor force, they were people who got new, better jobs.

That wave is definitively over in tech, and has been for about four to six months. The labor market in tech is slacker than it has been in a decade: it's harder now to get a new job in tech than it has been in the duration of many people's careers. And since people are not leaving the labor force, the quitting (to take another job) stuff is now much diminished.

This does not mean, of course, that there are not still people getting hired or people changing jobs -- just much less than before.
