In the past we have talked about elementary OS's software marketplace, called AppCentre. AppCentre offers customers a chance to purchase software using a pay-what-you-want model. The elemetnary OS team has some thoughts on the experiment so far and plans for the future: "One of the primary goals of developing AppCenter Dashboard was to build a sustainable app ecosystem. I don't think it's a surprise to anyone that although the AppCenter ecosystem is growing, nobody can make a living on it yet. That's what we mean when we say 'sustainable'. Writing apps is a real, hard, full-time job. If we want to see more high-quality, open source apps then we need to prioritize getting third-party app developers paid. Let's talk numbers a second. We released AppCenter in May 2017 and since then we've processed about $1,700 worth of payments from a little over 750 charges. On the one hand this is good because it means the average paid price for an app in AppCenter is about $2.30. We have to remember that this is a non-zero number in an ecosystem where previously the standard was zero." Further details and upcoming changes to AppCentre can be found in this post by Daniel Foré.
