One of the pros of the paid plan being "No more license key interruptions" concerns me, how often will it nag for payment? I understand needing to be paid but shouldn't nag screens be for trial periods leading to paid subscriptions not for "free" tiers? This concern stems from the giant full screen unclosable (no X at top right) popup offering me 20% off if I buy now before I've even finished reading the landing page.
