Wow.. I came to the comments page wanting to express my disappointment. I really wasn't expecting to see so many other people sharing the sentiment. I thought I was one of the last people in existence who deleted their Facebook account years ago and left it deleted. :)

The tech-sector is slowly growing into an oligopoly or at least that's my impression. I expect it to be diversified but deals like this leave me questioning and yes, they make me a bit sad. Perhaps the Oculus guys can use the resources Facebook will flow into them but...I have a bad feeling about this. Really.
The waves of patent and copyright attacks unleashed on Google are basically the giants who were born in the 70s and early 80s (Microsoft, Apple, and Oracle) trying their damndest to make sure no-one will ever grow in the shadows they cast.
