In reply to Ciprian Popescu.

Regarding Restrict Content Pro, I have replaced the plugin with WP Fusion, and honestly speaking, I could not be more thrilled. Solid plugin, extendable, and with rock-solid support behind it.

Replacing Easy Digital Downloads can be either done with AppSero (I do not recommend Freemius, at all) or WooCommerce with some additional development work, frankly speaking, I am uncertain at this moment as it is still a case study, however, both alternatives are somewhat viable.

Possible fork of EDD, perhaps, it believe it would require a team of devs to back it up yet I am uncertain how this will fall on the grace of Awesome Motive, as the company has the tendency to be quite aggressive when you mess up with their products.
