I tend to agree with this. Samsung made a big event of declaring their support for developers of Exynos devices, but have stayed quiet and slow in showing that they meant it. The Mali GPU is one area where access is still locked down to a binary blob, and it doesn't look as if that will change. The GPU is accessible under license to ARM partners according to ARM, though I've not seen it, and I think it's not Samsung's to give away unilaterally. There's competitive advantage issues involved no doubt, including the fact that Imagination GPU design, just down the M1 motorway from ARM, and used in the OMAP5, are locked down as well. The Exynos 5 dual core is a great device, but as in so much to do with ARM licenses, the peripherals are the work of the licensee. Texas Instruments use dual Cortex-m4's along with A15's in the OMAP5 which is a very capable approach when combined with good peripherals. I can see why Samsung would be cautious, but I do think they've been misleading in promising more than they could deliver. So far it just looks like a fork of Android Jellybean.
