If it's any help, WPE didn't alter WooCommerce at all. WooCommerce requires a separate plugin for Stripe payments, and WPE happens to offer their own payments plugin that competes with the official WooCommerce one (and works with systems other than WooCommerce at that).

MM continues to repeat the claim that WPE modified Woo itself, so WPE's lawyers are probably adding libel to the pile of claims. I think they're still waiting for a8c to file first for PR reasons.
