That is entirely false.
If the file has a copyright on it, unless it is otherwise noticed, you

cannot simply do whatever you wish with the file.
The moment you remove the licence is the moment you make the code

nonfree (e.g. non-compatible with any free or open-source licence).
If instead of removing the licence you put your own licence under a

copyright statement of someone else, well, that simply constitutes

fraud -- it's no different than quietly changing the first page of a

legal document after the document is already signed and approved.
