Seems like no one wants to admit that modern job-seeking is a living hell because it would mean that you're not skilled enough to be part of the "booming" software engineering market/economy that everyone else is seemingly a part of.
Compared to the people in this story, it's a totally different world, where candidates have a lot more power (partly evidenced by the fact that companies will pay for external recruiting help).
That said, I've run a few LinkedIn & Indeed job posts. It's frustrating when you see the same people apply for wildly different jobs over and over again. Whenever I hear about someone who's angry that they've applied to thousands of jobs but get no callbacks, I think about the candidates I see with no relevant experience, who've applied for a mid/sr level position only a week after they applied for a graduate level position. I get that candidates are frustrated, but as someone who's screening for people, it won't get you moved forward.
