I don't disagree with anyone that is wary of Oracles motivation with this product. I also don't disagree that the product itself is nice. But given Oracles known interactions and history with open source an attitude of "fool me once, shame on you, fool me twice, shame on me" isn't unwarranted.
We already have that, it is called CentOS. If giving something for free means trying to trample another open source project, then 'No Thanks, I think I'll pass'.
I don't think Android's developers should feel super duper sad that they killed Meego's chances of rising from obscurity.
This can be interpreted as an attempt to suck the air out of CentOS and Red Hat at the same time. Considering Oracle's past, the hypothesis cannot be ruled out easily.
