Companies that POST jobs, but already have an internal candidate in mind and waste everyones time – this setup should be Illegal

I hate applying for a job, time wasted interviewing, suspense waiting, and hope shot down because they never planned on hiring externally in the first place, this should be illegal. —— We appreciate your interest and taking the time to speak with us about the Tech Support Specialist III role. After careful consideration, we have decided to move forward with another candidate at this time. To give more detail: it was filled with an internal promotion.  We thank you for the time and effort you took to apply, and understand that this kind of news can be disappointing.
