Sadly RouterOS isn’t open source. They’ve received a bit of flak for their “available on request” stance on getting GPL sources too. The fact that their GPL patches aren’t readily available is pretty uncool.

If you have any more details about the GPL issues with Mikrotik RouterOS, I recommend reporting them to the Linux developers via Software Freedom Conservancy, who have copyleft compliance projects:
