This. The JetBrains licensing model is great. Subscribe to get updates, with a perpetual fallback license for the last version when your subscription lapsed. Their old versions also continue to work across OS upgrades, etc. If you subscribe, the annual fee decreases substantially for the first few years. This is nothing like Adobe's Creative Cloud.
I thought their fallback perpetual license is actually for the version you had when you purchased it, not for the version that was available when your subscription lapsed?
Not sure if they changed this recently - I stopped following them when they switched to subscription with fairly onerous terms (which they rectified after backlash to ‘mediocre’, but never to ‘fair value’).
You're correct in that the current terms are a result of community backlash, or at least that's how I remember it. What would you consider "fair value" for such a tool? And does that include any period of updates and enhancements?
