It's not even about that, but about the brick code being present in their launcher. It didn't magically get there. That was written with the specific intent to brick a user's console.
No doubt their is code there that causes a brick, but for it being intentional, we only have the word of "trusted" people. All from the same inner circle if you will, all with an anti-piracy stance.
It could just as easily be the anti-update code they were working on (that they already said bricked their test consoles) left in, that is bugging out and going wrong. It apparently locks the emmc (not wipes it like originally thought). Sounds more like something to prevent accidental updates (lock emmc, update emunand, unlock afterwards), rather than intentional brick code. Of course they could have adapted that code to be used for bricking, but, If you have an anti-piracy agenda, what's more damaging to the cart
They intentionally bricked stuff
It's a bug
Think about that.
