Doesn't the Flint 3 require a binary blob to run the broadcom chip? If so you'll always have a locked down black box inside your "open" system.
I got the Flint 2 to avoid that, and I'm really happy with it for the reasons you mentioned.

BTW, even though there are mentions that OpenVPN is accelerated on this router, WireGuard is still times faster. I had to switch from ExpressVPN to Proton as ExpressVPN doesn't support WG profiles.
