They put hardcore DRM in a tool that literally enables piracy on the console. Pretty ironic. Bricking consoles is not a good thing, believe me. If a big AAA company started to include a DRM that breaks your computer, they'd be drowning in lawsuits. But even ignoring all of that, the brick code that TX included was pretty likely to activate on its own, essentially fucking over innocent users. I don't care it it's gone or not. Even if they really removed it, my respect and trust towards TX has dropped drastically. I don't want to pay 30 bucks for a closed-source piece of homebrew that has the ability to brick my console. This is one of the things that ruin many scenes.
And no, they are in no way "original". ReSwitched and fail0verflow basically discovered the exploit, while TX just used it in their shitty commercial product.
