With this update, ExtraStorage is now open source. If you are a developer, you can now access to the source code and make changes and contributions. If you are a new user and want to test the plugin, you can now access to the source code and build the plugin yourself for free. However, the support server is only for those who bought the plugin. There will be more major updates since I'm planning to replace the current codebase to one that uses my library.
If you still continue leaking this plugin, at least don't put it behind a paywall (require paid ranks to access the plugin, etc.). Since the plugin is now open source, I want users to have an option to test before buying. So again, make it easier for all users to access the plugin and don't put it behind a paywall.
