"Knowing people" seem to have become even more important. But I feel that is a really long term thing. It is really hard to get into a position where you get valuable contacts or do interesting stuff. And your contacts more or less need some power.
It is just that, I feel it is like telling some lonely child "so get friends". For most programmers trying to get a job, I think "just keep the grind up, champ! I'll buy you some ice cream if you give it your best" is more helpful.
These "ghost jobs" the article writes about is poisoning the well. Applicants need to spam even more. Employers get more half hearted applications.
I've noticed these probably fake job ads for years, but it seem to have escalated.
It wouldn't surprise me that we will end up in the straw man "first man or woman through the door with a firm handshake that looks the boss in the eyes gets the job" hiring process as the current formal one gets totally dysfunctional.
