Hi Gassho,
We are the new theme shop at that time and we have not integrate any email subscribe service and also we think that we can not send an email to premium users because they have not subscribe to our newsletter but when it comes about the security issue in the theme then we think that it’s our responsibility to aware our premium users about the revolution slider critical vulnerability and decide to send an email for all our premium users to update the plugin.
Who knows the future if we know it then we will be sure that we will never packed it inside the theme. We packed it inside the theme for only to have more flexibility on the theme slider and it was the most popular plugin as well.
Also we have already updated the theme with fixing the deactivating issue in the Revolution Slider Plugin.
Thank you!
