It will get you around ISP and network level blocking, with high bandwidth and considerable less privacy concerns than any other free vpn. It is not surprising that you will need to pay money for geo-spoofing, and due to the nature of it’s design it can only expose your client IP to cloudflare customers. As far as VPNs go, those are very minor restrictions.
Saying it isn’t a VPN is pedantry and also wrong no matter what they say.
