You not getting the point, we are talking about software exploits not hardware mods. Sky3DS is been there as always, of course it is a hardware mod that is not in control of Nintendo at the moment (well sort of just recently been patched). Software exploits usually are free to share and spread for free, and if the company keeps failing on that then the developers would eventually think that way you know...
If Brahma works on Ninjhax and (eventually rxTools and CFWs) on 10.x which is the latest firmware and works so easily without any extra hardware...
PS. excuse me for several edits as I using this forum on my smartphone... also now I don't want to take it off-topic so I end it here
