Just read some comments there - I think some of the zealots are offline due to a stroke. Normals trolls are immune to this, so they are still there.
Basically the tradeoff is clear and argued all over again and again. Force the sharing ./. share by gift (as if you could sue someone for violating the GPL and then show up in court with reassemblies of encrypted binaries you somehow picked out of a secured, closed system like some game console... not gonna happen).
What I find quite disturbing is the tendency to deny developers to choose what licence they want. WTF? Can someone please grow up? When I put code under the BSD licence, it's my choice to do so.
The PS4 is said to be pretty different from off-the-shelf HW, so I see no point in Sony not giving anything back. On the contrary - doing so would make sense. You need not keep it up to date on your own that much. And when finally someone else may find an architecture sufficiently close to the PS4 on the shelf, well, I think the PS4 will be considered gone by then. So no loss there. Only more developers who already know the ropes and can make things for the then-hot PS6.
Some of the posters there seem frustrated that they don't get asked to nitpick on the brushwork on the bikeshed. Not that they would have any choice in the paining, or the color, or the whole blooming shed.
