The content of the blog link does not make the difference of being a company member of the ObjectWeb consortium and actually supporting an ObjectWeb hosted project.
It is not because MySQl AB joins ObjectWeb that ObjectWeb now almost covers the enterprise application stack.
Tomorrow we could decide at eXo Platform SARL to pay the 1000 euros entry fee that would not mean ObjectWeb would get a portal.
Furthermore for MySQL, like for us, and unless ObjectWeb changes its policy it would never be possible to introduce a double licensed project in the forge.
So indeed, the consortium contains many actors from almost all the enterprise stack but the ObjectWeb projects are not.
Don't take me wrong, ObjectWeb is a great organization with a very strong industrial support (many ISV - and especially french ones - that contact us ask for a JOnAS support).
