There are no limitations on this version of the plugin other than what is spelled out in the GPL licensing. We have not launched our pro version yet, so no there are no paid functions available at this time. And we won’t be introducing features in this version that have to be unlocked by making any purchase.
When we launch the pro version, we will be providing a way for anyone using this free version to obtain the pro version, but we will not be causing this free version to connect to any service other than what the WordPress platform already uses for the WordPress update system.
There are certain optional social features available with this plugin, that you wold have to set up, which can connect with other social platforms. You would have to make those connections, this plugin does not do any of that automatically. Those connections would be governed by the rules, policies and practices of those other social platforms.
