Dude… The free version actually has more features than the free version has had for the past 4 years!
The free version allows you to protect any page/post/cpt by having the user have to purchase the page in WooCommerce before viewing.
The Pro feature adds additional protection types like pageview protection, time-based protection, etc.
For you to say it has zero customization is completely false, and for you to say it is completely useless, you can tell that to the 1000+ people that are currently using the free version.
I really wish you would have reached out first before writing a scathing review. Bummer.
