Are you talking about Powersave_NTRBoot? Just so you know all open source Github projects are PUBLIC and as such, can be disseminated without the permission of the developer. The source code is another matter, and depends on which license was used. Though most Github projects use a GNU license (which you can always check) so they literally can't get mad or stop people from linking their programs or forking them with the open source code.
I understand being considerate to developers in the sense of asking permission before sharing their private work, but public freeware doesn't hold the same merit. The best example I can think of is the guy who made the borderless gaming program for Steam under GPLv2, then when it became popular he tried to backpeddle and change the license to MPLv2; and only providing builds through steam. When the original program (before the MPLv2 license change attempt) was forked and providing compiled builds the guy tried to issue a DMCA but couldn't because that part of the code was under GPL at the time. Basically dude made freeware, it got popular, others added code, he got greedy tried to sell it through Steam only without providing compiled builds on Git and still using some code submitted by others under GPL. Long story short.... He was forced to revert the license back to GPLv2.
