Ay, we're arguing semantics here.
Wikipedia: Invest => To allocate money in the expectation of some benefit in the future. Investors generally expect higher returns from riskier investments.
You can spin it however you want but these are projects that are inherently super risky. If they were a sure thing they would be getting funding already. Kickstarter is also especially skewed against the backers because you are bearing the entire financial risk of the project and in return you are expecting just to get what your money back. Its great for companies. They get their funding, own complete rights to their products, and if they run out of money, theyre back to where they started. Meanwhile, youre shit out of luck.
If you're cool with gambling your money away, thats on you. And absolutely back stuff that you are passionate about. But me personally, I just expect better odds.
Patreon is a lot less risky. Theres less commitment. Much shorter time frames. Different deliverables.
