F-18 is like Apple device. You can't install uknown apps or cracked apps (unless u r pro cracker/hacker). Seems to me the F-18 software provided to Malaysia has a lot of restriction. And to get source code? No way US gonna give the source code, someone can leak it to CCP and built their own F-18. So buy Russian planes (maybe Windows alike?) and crack it and install any programs u want.
