No, the financial sense of the word "investment" isn't the only meaning that matters here, because here we're discussing the behaviour and attitudes of contributors. Its unreasonable for anyone to expect them to ignore their emotional investment and only think of things financially. If they did that, they wouldn't have contributed in the first place, and Oculus would not have gone anywhere.

Oculus benefited greatly from selling itself as the future of VR gaming. That was the image they cultivated, that is why their Kickstarter was so successful. That is why people contributed. The Facebook deal most likely means a big shift of focus to social VR. There's a big difference between hoping a company will share your personal values when it gets successful, and being sold a particular plan which is then abandoned in favour of a big payoff.
