I'm really hoping it works out, and Cloudflare can continue to contribute their expertise working with WG. At the end of the day, this benefits everyone since OpenVPN whilst it's reliable in my experience, is just too burdensome.
I also am intrigued by the price, and features that will differ between free/pro. I suspect many VPN services over the next few years will feel the effects of this (is that why they're all rushing to add 3 year plans?)
