The "bizarre" world is this world.

If you go through the trouble of applying for a job, submitting a resume, doing a phone interview and are rejected - they may kick you to the curb and NEVER tell you why. This is not bizarre world, this is this world.

If you apply to college and they turn you down, even though you have paid fees and spent time on your application, they almost certainly WILL NOT tell you why as they kick you to the curb.

If you are sending spam and the mailer rejects you, it almost certainly will not tell you exactly why - just give a link to general guidance.

Most if not all large / high volume application systems have evolved in this direction.

I'm not saying it's acceptable, I'm just saying— the alternative is probably something more like the five-figure game console SDK license fees of the PS2 era. That kind of money pays for you to have a phone number to someone who is accountable for your success deploying product on the platform and helps you work through any issues you come up against. But obviously, it also locks out most smaller devs from participating. So it's arguable whether the current state of affairs is sustainable or a net improvement.
