Ignorance would be misunderstanding or even misrepresenting the actual license with the wrong license. I maintain a FLOSS project that ships libraries with various FLOSS licenses, and it's within the realm of possibility that somewhere in there is a README that conflicts with the license at the top of a corresponding C source or header file. (Hypothetical example: README says gplv2 and the c file is 3-clause BSD.) But removing a copyright where condition #1 is a single sentence that tells you not to remove the copyright? And replacing it with a different license? That certainly isn't ignorance.
