Thaer,
I believe that the DCMA filing by Monero against SumoKoin also applies to the Masari code . See
https://bitcointalk.org/index.php?topic=1905086.msg29047236#msg29047236Basically the problem is that the Masari code has indeed modified the copyright statement which does not show the original Monero copyright. Also is suggest that you do not add Masari copyright to files which havent any real contributions by Masari except for function/variable name changes. This always bothered me, i had noticed this in Sumokoin then too.
I suggest looking at some other project (linux kernel my fav) to see how copyright assignments are done for new modifications. It better to rectify now than later.
