To be fair, Yakara is actually a nice guy, he fucked up big time, but he changed the uploaded files asap, even tho that doesn't change anything... Yakara has never claimed any of the developer's stuff of his own, he has always said that he just made things easyer to people that doesn't know how to read english or shit and want fast help, and also, yakara has ALWAYS said that this wouldn't be possible without you guys, the great devs out there making the 3DS modding scene possible, he says that in every single video i've seen, so, yes, he fucked up, but he've never claimed your code to be his own...
About Tcpixel, i feel also really bad, i enjoy the way he talks and everything he has done for a bunch of people, both of these yt'bers were gold for the community, imo.
