It looks like the goal of the eclipseide.org
page has changed. Most users won't really understand it. IMO, talking about the "Working Group" first is not the best strategy to engage new people in Eclipse IDE and the Working Group. It looks like "selling" the Working Group is the priority more than "selling" the IDE and I don't have the impression it serves any of both better.
I would recommend that the eclipseide.org
page reverts to the content of eclipseide.org/release
page; and that this page shows a more explicit part about the "Product Governance" referencing the working group.
