Call me cynical but this situation is the exact reason I have never and probably will never contribute to a kickstarter. First of all: irrespective of how dishonestly kickstarter projects advertise themselves, kickstarter itself has always been entirely clear that you’re not buying a thing but investing in (hopefully) making a thing into reality and if that is achieved you will get the reward for your backing.
Secondly: c’mon people… if something is a truly great idea, just wait for it to be product you can go out and buy. Your contribution alone will never mean a project reaches fruition, so don’t be a sucker and just wait.*
*cue angry kickstarter purists telling me my mentality derails the feasibility of the whole thing.
