Just like all 3DS Games and Applications out there in the world? This looks like the most normal thing in the world to me.
I don't see why you are so negative about this.
EDIT: Also this prevents malicious homebrew that wipes your system nand and things like that. So Gateway is only looking out for its users
They're only looking out for themselves, because allowing any permissions would allow functionality that would render the gateway obsolete, such as being able to install any title to the SD card, perhaps modify and create a permanent cfw, and so on.
The reason I am being negative is that it was expected that this update would help blow the system wide open although it has done the opposite since it's more limited than ROPloaders. Additionally, they have disabled every other signature check so it was kind of expected that anything would be possible, instead they have figured out how to make use of a built in function to enforce basic DRM and keep their hardware from becoming obsolete.
While that isn't surprising, I was not aware of the accessdesc requiring to be signed separately from everything else as no one had mentioned it, so I had no idea they would be able to do something like that.
I was hoping this would make it easier for devs to release more advanced system utilities and tools, like save editing and encryption, not things to make the gateway obsolete as I am quite satisfied with mine, but just some useful things for tinkerers and users alike. At the very least I would have liked if they manually enforced certain permission restrictions which would be more lenient than what we get now, without restricting access to every small part of the system.
I've been waiting for a way to be able to edit and sign save games for a long time and I was hoping this would make that easier to achieve. I am a guy who loves to tinker with things and do things he's not supposed to, i always root my Android devices, I always install softmods and buy flashcarts/modchips, and I often install windows system tweaks as well as customizing the hell out of any Linux install I have. So you can probably understand why I'm upset that the only use for homebrew on the 3ds now is games and emulators, and maybe a video player.
