They say their plan is to both release it for profit and continue to support it, all under the constraint of a limited number of user tokens provided to them by Twitter. I wonder if they considered a subscription option instead of a one time payment. A lower subscription price (say a dollar a month) might have sounded good to users psychologically, kept a revenue stream going for the stated future development, and offered the potential for recapture of user tokens as users drop out of their ecosystem over time for whatever reason, which they could then convert to revenue again. I really have to imagine that they at least considered it, -I'd love to know why they decided against it.
