Many use the philosophy of "Do not force it get a bigger hammer" and can get all sorts of things to fit were others have failed.
From an old saying about 8.5 inch floppy disks:
There are 8 ways to insert a CF card into a camera, only one will provide a unique and desired result.
It is possible to carefully move the CF card in and out of the contacts and have the movement remove some surface corrosion. If a card is always left in the camera the chances for oxidation to build up is lessened than if the camera is stored without a card. Also keeping cards in a sealed case can reduce corrosion.
