As mentioned by a few others here and on FB, this LTD is converting to a subscription pay model. Why do we even bother buying LTDs if companies can reap the benefits of infusion of cash from the exposure of AppSumo and find a way to turn around and not honor the original deal? Yeah, it's a risk to buy a LTD, but that risk is usually the company goes bust. These guys didn't; they are changing the rules. Based on their email, they sold the intellectual property to new ownership almost 3 years ago. Now after they sold, they are justifying charging an Infrastructure Maintenance fee ($5 / month) or you need to become a premium paying customer so they can "keep the lights on" (as they state). What is frustrating for AppSumo buyers is the not honoring original deals is a nice loophole that can be exploited by anyone selling a LTD on AS and essentially nullify your purchased LTD deals. This deal should have been one with a time limit, not a LTD because clearly it is not.
