Well all three response examples would be a lie if they then keep the job open, which might trigger some people into more back & forth ?

"we are sorry to announce you we decided not to select your profile for the next stage of our hiring process"

Oh I agree they should send a response, I just disagree theres any incentive or information for them to provide a reason!

There's an incentive to be nice.

Moreover, candidates might prefer bland non-responses that demonstrate more savoir faire than explaining, honestly but stupidly, the reasons of a rejection.
