With the PS3, we shared everything. It was an experiment, to see if the community could handle building a homebrew community without handholding. It couldn't - all we got was warez tools, waninkoko bricking consoles, and a lawsuit to deal with for naught. That was pretty much the signal that homebrew on home consoles is going downhill.
Homebrew on home consoles had a reasonably good run - one generation (PS2/Xbox/GC) happened when security was in its infancy, hardware was still simple enough to understand, and the hardware required was "free" or affordable. Then the Wii really peaked, since the community could leverage most of the GC work, there were even more free exploits to serve as an entry point, and persistence was easy. The 360 was a good example of what was to come security-wise, and the PS3 a good example of what was to come complexity-wise. The community couldn't handle those - even when exploits appeared, all that happened was piracy. Now we're in the next generation, and it's time to admit that consoles have become too complex for small teams of homebrew developers to truly understand. The only potentially saving point is that both the Xbox One and the PS4 are "basically" PCs, so if you can just take over the console completely, you could throw a desktop OS on it and maybe reuse most of existing drivers developed for PCs. But with the ability to buy a comparatively powered HTPC for a similar price as a game console, and things like smart TVs taking over some of the use cases (there's a good reason why some of the most popular homebrew apps for PS2/Xbox/Wii were media players), the interest just isn't there.
If you want to prove me wrong, feel free to bootstrap a proper homebrew community and development tools. If you want warez, go fuck yourself.
