Yeah, the whole article reads very...coroprate-y.

I'm not sure if I'm happy with it, but I haven't used Gnome in multiple years, so my opinion doesn't really matter here. I do however, wish that Gnome foundation remains healthy. Having competition is always good, even in FLOSS.

> The goal is to find projects and funding that allow us to both invest in the GNOME community and find new ways for FOSS to benefit people who aren’t already in our community.

The statement of their specific goal for the future refers to FOSS.

Given that the mission statement of Gnome is explicitly "to create a computing platform for use by the general public that is completely free software." I'm not sure why it would.

Open source as defined by the OSI is literally identical to free software as defined by the FSF.

And no, open source does not include things like unreal engine which you can view the source but not use freely. This is called Source Available software.
