There is something more serious than migration and price increase. By migrating to mailchimp you are agreeing to mailchimp's terms and service. If I understand it correctly, now they can read all your customers' email address and content (presumably for machine learning & send optimization). This is in direct conflict with the agreement we signed with our customers on data sharing. Unless I am mistaken, this seems to be deliberately omitted in mandrill communication to mislead and collect data to create "network effect" from our customer data.
