If you actually bother to read the Federal Register text, you can see in the second paragraph of the introduction that the JOBS Act, and this subsequent regulatory structure, only applies to crowdfunding where the reward is a security. It specifically explains that this is different from the current model of crowdfunding in the U.S., where the donors receive some "token of value" related to the project, not a share of future financial returns. The SEC isn't trying to regulate the current system, but is trying (as directed by that law) to allow crowdfunding where the donor award is a security; the current regulatory structure, based on the Securities Act, largely makes this sort of model impossible due to the various requirements of public offerings.
So, there's nothing to get up in arms about. This is just a move by the SEC to allow something that isn't currently permissible under U.S. law, not an attempt to "tax Kickstarter" or "regulate Indiegogo" or whatever other nonsense people claim.
