What's different as compared to before? I apologize for being ignorant, but I have no idea what is a key in that context, so I do not understand why it suddenly is a problem.
Scires (and ReSwitched in general) cannot and will not distribute the key as they do not do copyright infringement which is what distributing the key would entail (and is strictly illegal and any one who does "leak" the key is actually putting themselves in an exceptionally bad position legally speaking). They also won't "accidentally" leak the key to someone else to leak, and as of right now only a small handful of people know the flaw, its execution, or have access to the keys, and all of them are either (a.) not going to leak it, (b.) have quit the scene with public releases beyond PoC because their work was taken to do nothing other than piracy, or (c.) both (a.) and (b.).
(If the key magically leaks online, also, it becomes rather obvious where it came from as only ReSwitched/Switchbrew have shown any PoC, and they're easy to find.)
In the past RCM flaw made it trivial to give users a program to dump the keys because the flaw was ubiquitous and public (so nothing is lost when making the tools). The current flaw is software and can be patched, and no one wants to burn it, so that's not a viable method of giving out tools to dump keys. The moment they share the flaw, it will be "burned" and lost come another firmware update and putting everything back to square 1.
So no key = cracked 6.2 but no way to use it.
There's nothing wrong with hacking a console imo and it's interesting to see what talented people can come up with for exploits and homebrew, it's just there are a few idiots in the hacking community (not giving credit for code, piracy, cheating etc that spoil it for everyone and those "few" are enough for it to be a problem.
Said idiots have chased away key members like Naerwert. He no longer releases *anything* because the moment he had before, it was immediately turned into a backup loader for piracy. So he just told the scene to shove it and left.
