I'm saying that the former is a bigger problem than the latter. You're absolutely correct that consumers need to inform themselves properly before backing a project and delays are to be expected with something as elaborate as your average videogame. However, as it is now, there is no repercussion whatsoever for devs deliberately overselling their product, promising for features they know won't ever make it into the game and just outright deceiving their backers. Developers can make massive changes to their plans, seek publisher help anyway or just abandon the entire project outright and the backers just have to "hope" their money didn't go to complete waste every single time they back a product.
Yes, sometimes devs genuinely fuck up and the entire project goes to shit, which is always a possiblility, but the amount of incompetence or just outright fraud is absurd and the system does nothing to combat that.
No "release what you got to the public" kind of rule, no retracting, no transparency rule, nothing. There is literally nothing the people in charge of funding have any say in or any control over. The only thing system more anti-consumer than this is early access.
People should be well informed and understand that game development is complex, but Kickstarter should also at least take some steps to make it less easy to abuse the system.
