Love the JetBrains model. Another viable option is "moderately priced one time purchase that includes free updates to the core product forever". This seems to be working fine for FL Studio over the last 20+ years. I think three of the reasons it works for them are: * feels like a great deal and so produces word of mouth that leads to extra unit sales. Anecdotally, I have definitely observed/experienced this personally * indie musicians are (probably??) relatively easygoing & forgiving as far as desktop software customers go, meaning that long term support costs prob take a relatively small chunk out of the one time payment * there is a steady stream of relevant and compelling but completely optional upsells to drive further revenue, in the form of (both in-house and third party) plugins and sample packs
