You don't pay to develop; You pay to have a server that works with Graal, that processes codes, and that outputs them via a spcific client. Whether you use it to enhance Graal or not is ENTIRELY up to you. Like #gscript doesn't use the Graal Servers as a development; they use it for their own community.

If you do have good content that enhances Graal, your subscription is frozen, meaning you don't have to pay anymore. That said, I hope that you look at this in a more objective way.
