This post discusses the concept of one-time purchase software and the challenges associated with it, particularly when it involves server-side components or potential obsolescence due to lack of updates. Users express concerns about the reliability and longevity of software advertised as 'buy once' but which may require ongoing support or subscriptions. Key points include critiques of certain products that claim to be one-time purchases yet impose time-limited updates, and a lack of transparency regarding the dependence of some software on online services or subscriptions. The community also highlights past experiences with software that began with a one-time purchase model but later shifted to subscription services. Overall, there is a call for more clarity and honesty in software licensing to preserve the integrity of the 'buy once' promise.
