Example:

A1: 1 B1: 2 C1: =A1+B1 (result: 3)
A2: 2 B2: 1 C2: =A2+B2 (result: 3)

Now you protect cells C1 and C2. Now this is an important spreadsheet to
customer and their employees fill the data to cells A1, A2, B1, B2. And it's
of course important that the calculations are correct.

Now the customer enters data to A1 which was supposed to go to A2. He/She
cuts the data from A1 and pastes the data to cell A2.

This is the result:
(he/she wanted to enter 1 to A2, but entered it to A1 and then cut + pasted
it to A2. Then he/she entered number 2 to A1)

A1: 2   B1: 2   C1: =A2+B1 (result: 3)
A2: 1   B2: 1   C2: =A2+B2 (result: 2)

So the formula in C1 is now A2+B1 which is different than A1+B1 so it
changed. And since the cell is protected, you can't change it back to
correct one unless you cut + paste again. But if the formulas are also
hidden, then it's totally impossible to fix it anymore.

I've heard some comments like "This is expected and wanted behaviour in all
spreadsheet applications.", but then I would like to ask what's the point of
protection when you can't protect the formulas from even the simpliest user
errors? I know that this happens in Excel too, but there you are able to
prevent user from using cut+paste (and if googled, you'll notice that people
use this quite much just for this reeason).

If this is a wanted behaviour, it should atleast give a warning to the user.
"Are you sure you want to cut + paste data? It will modify protected
formulas and you won't be able to fix those anymore and you will get wrong
results afterwards? So are you sure?" :-)
