Most of customer misunderstood the meaning of no paid plugin required.
Three plugins will be required and other are recommended, Choice is yours whether you want to have them or not. Your theme will work properly without them.
No paid plugin required
Means we will provide all the latest updates of the plugins with the theme updates. It doesn’t mean we are going to provide license of the plugins as these are third party plugins.
Why you need a license of the plugin.
So that you can ask for help from the plugin author regarding plugin issue, which you won’t need to. As we are providing all the updates with the theme updates.
