To reply to stevejnb's cynical reply above I just want to add that clearly Kickstarter backers wrongly thought that the quaint notions of LOYALTY and TRUST still existed in independent (i.e. non corporate) communities, and hadn't yet been entirely replaced by BETRAYAL and GREED. Clearly they were wrong, and presumably will have learnt a valuable lesson.
Just got to ask, do the people who gave money to this project figure they were donating to a non-profit charity organization? The moment you donated to a project that was going to become a consumer product, you really shouldn't have had any illusions about there being any endgame to this other than making a lot of cash.
If you donated, you were NOT betrayed in any way, shape, or form. You gave money to people who wanted a kick-start to make a consumer product. The whole point was to get their product done and make money off of it. Getting bought out by a big company not only fulfills both of those goals better than keeping it a rinky-dink kickstarter operation, but it also gives this product the backing it will need to get truly big.
I have trouble believing that this wasn't their plan from day one. Really, what was everyone expecting? Get enough money from Kickstarter to design a prototype and then kickstart for some tiny production run, likely too small for serious PC developers to dump significant resources into supporting? Maybe claw their way into the big league over the course of years if some other company didn't just come out with their own VR headset that instantly had massive resources backing it? That's a recipe for the OR being the VR helmet equivalent of the MP3 players that came before the iPod. A big company that actually has money and industry pull to back it was likely their end goal from the start. Otherwise, it would just be an idea that never had a chance to be really big due to lack of resources.
You didn't get betrayed. You went in with ridiculous expectations and are personally offended that a business wanted to make as much money as possible.
