It is usually common courtesy to tell at least what part is being exchanged in the process. Say, they would have made these two additions:

An update in February: "SIM card holder investigation progressing. We are currently suspecting the left flange as the problem. We may also need a firmware update. Will keep you posted."

An update in March: "OK, investigation complete. If you have issues, we'll update the firmware related to the SIM card sensor. For those whose left flange is faulty, we'll replace it, but it is not necessary for most."

That would have been pretty open and certainly much more useful for the participants of the thread than the non-answers they now got.

Jolla's rep was about to tell the reason, but then for whatever cause they decided not to tell it.

Just read the thread:

It definitely would have served a purpose to provide information in that thread, in my opinion. Now it looks pretty weird to hide it so deliberately.
