Well Easy Restricted Content for WooCommerce 1.2.1 is now out in the wild and it has a fix and a new requested feature.
It seems that 1.2 gave you the wrong link by default when you restricted your post/page/forum by a variable subscription product. I tried to link to the individual variation instead of the product that held the variations.
Now it links to the product properly.
As of version 1.2.1 you can now restrict content by multiple products. So that means if you were selling an eBook and had a page that was for purchasers only you can assign that eBook as a product on your page.
Then you could assign a subscription that was intended for users to access all your books as they come out.
Now a user that had purchased either the subscription, or the single purchase book could see the content.
