Title is inaccurate. Amazon did not force Unglue.it to suspend crowdfunding; it merely forced Unglue.it to stop using Amazon as the backend for their crowdfunding payment system. Also, the license for the ebooks and the distribution model were irrelevant to Amazon's decision. After all, Amazon sells/gives way plenty of CC'd books. As other comments have noted, Amazon has decided as a matter of policy not to accept new crowdfunding customers until the legal and regulatory issues (i.e., money laundering, refunds, undelivered goods/failed projects, etc.) are worked out. You can still use Paypal (takes a long time to get approved) or Stripe (you must set up your own backend). Alternatively, you can go directly to a card processor (but you must then satisfy very stringent and expensive security requirements).
