I'm asking what usually people do not want. How can I give permission to copy my document? I mean, I haven't add some kind of obstacle, I can copy the titles, and some text that is in underline, bolded or in italics, but not the main text. The document language is in russian, but as I said, I can copy the titles, etc.
This is the mutavel style (short version, also could be downloaded from https://github.com/protsenkovi/latex-ssau-gost-style), I couldn't find nothing that generates this situation:
