Virtually every company tech and non tech is guilty of doing this.
The spare parts you buy to find out that they only fit a model made up until X date provided the serial number is less than something.
Just try and buy spares for a car without the chassis or registration number you will find a subtle difference where the replacement won’t fit.
I had a bmw where one year into the production run they changed the door lock mountings as a result you need to check the part number against the chassis or it won’t fit. But look at two with the different doors and nobody can spot the difference as it is all internal.
Biting the hand that feeds IT
