Sony isn't releasing there (ps3) opengl wrapping code are they? They only have to offer their modifications to the actual opengl libraries. If you add a custom an unique piece of software, that uses a gpl product, you are not required to gpl your custom code. If you make modifications to aan existing gpl project, then before releasing your version you are required to submit the changes to the upstream developers.
I'm not an expert, but I think that things you mentioned above apples to LGPL not GPL. AFAIK LGPL allows dynamic linking to library's but disallows to modify them (if you modify some part of it you should share yours modifications with community). But GPL is a "virus" license as far as I understood this it means that whenever you use GPL software (it doesn't matter if you are just "dynamic linking" to it) you should share yours code ... I'm might been wrong, but from my point of view this is the main reason why software company's do not use GPL software in theirs solutions ... but can use software released on LGPL licence.
