Some games, sure. Some projects simply won't find business investors so the way to do it is through crowdfunding. It's not about taking the risk while the company gets the profit because they won't profit unless after the crowdfunding the game goes on to sell a lot to non-backers, which would be possible but rare.
There are two sides to it in the end though, one bad and one good. Bad is creating a precedent that makes the companies shove too many things to crowdfunding and not funding anything that isn't 100% safe. Good is that a "type" of product that first requires crowdfunding to find success or a market can then go on to actually expand through proper funding (whether it's the same company or a different one looking to copy the formula), exactly because that particular title was very successful. What actually happens depends on a lot of things, including the success of the projects and the mentality of the corporate heads
I sure as hell would help fund some dead IPs I love and that the owners are clearly unwilling to fund due to their relative failure.
