It is not a problem with tech hiring in general, just hiring where there are millions of people lined up down the street vying for the same position. To be sure, the job will still most likely go to a friend or relative, but if you are willing to jump through insane hoops you might also be considered. But it is to be taken as a hint that says: "Unless you are extra super sure that you are so special that we can't turn you down, don't waste your time, or ours."

Most other jobs, including Mom & Pop Tech Co., are happy if anyone applies at all and will take what they can get.
