The backlash is a bit silly, though I also find the acquisition surprising. I suspect that companies with any sort of capital investment in a rift-based-game will continue development.

That being said, Oculus owned by Facebook is a different sort of animal than independent Oculus. Previously, they had to sell the public on a $2-300 VR gaming headset or die. Now they have a lot more wiggle room. Personally, I feel more comfortable working with companies that have as much skin as I do in the game. I understand why the shift would unsettle people.
