Facebook buying Oculus is a good thing.
Facebook Inc. is a public company now. Facebook the platform is just one thing that Facebook the public corporation does. The same way that search is one thing that Google does.
Google also does driverless cars, and maps the world, and makes thermostats. The same way Facebook also does mobile data compression, pictures and now virtual reality.
All companies need resources to grow and scale fast; especially young ones like Oculus. Being acquired by a very well funded parent company is a great way achieve this. I couldn’t think of a better funded and more focused partner, and one possessing such incredible problem solving skills than Facebook.
This is a good move for Oculus. Good luck. Move fast.
