Coming from free Drupal contrib: making peace with Craft's paid plugin economy
Opening Craft's Plugin Store and seeing a price on the field type you need is a values-level culture shock for a Drupal dev used to free GPL contrib. How the money works (20% cut, one-time + annual renewal), why the paid model is a feature disguised as a tax (maintenance funded by self-interest, not goodwill), and the real lock-in: 'we stopped paying' and 'we stopped getting security updates' are the same sentence.
