The issue is a mismatch of incentives - customers wanting things for free - even if they aren’t actually customers. Vs businesses need/want for ongoing revenue (ideally for free too!).

There was a comment here recently — someone complained that SoundCloud doesn't treat "former paying customers" well. This complainant was a "former paying customer".
Free customers can store 3 hours of sound. This former paying customer had more than 3 hours of sound stored.
