Let’s create the most expensive GPL licensed WordPress plugin and call it the Pricey GPL. It is offered as a free download from WordPress.org and by default it displays a random paragraph from the most downloaded book at Project Gutenberg in the WordPress dashboard. Of course, there is a widget available, too.
However, to enjoy the real value of the Pricey GPL, you have to purchase a monthly subscription to the PriceyGPL.com service (an API key) which displays a random paragraph from one of the GPL licenses.
- Can software released under GPL be pricey or does it have to be a service or a subscription tied to it which can be pricey?
- How are these two ways of pricing different from the users’ viewpoint whose rights the GPL is protecting?
