Virgin, which is notorious for throttling and blocking VPN connections, and also general speed issues during peak times due to over-utilization of their network
Ah yes, the infamous "throttling" and speed issues... I read a lot about VM throttling VPN connections, and even wondered myself at one point. Then I spent a couple of grand on a decent PC, and completely overhauled my local network with all copper Ethernet, a decent managed switch, OpenBSD x86 router, and Ruckus R710 enterprise WiFi.
Strangely, VM seemed to stop 'throttling' my connection after that. Or rather, they just don't. They actively confirm on their website that there's no protocol throttling, shaping or 'traffic management'/slow downs any more. They got rid of that a few years ago. You won't get what you want out of your network unless it's built and running properly. Pick a time of day, all over WireGuard to (variously) Mullvad, PIA and Nord.
...Throttling...
The 19.2% figure only shows availability, the number of people that actually have full gigabit is going to be much lower than that.
That's by the by though, isn't it? And a nice little straw man. You can't say that WireGuard is pointless and unsafe, and that OpenVPN is fast enough because only 12% of the population have FTTP... But then, faced with evidence that all of those arguments are false, say 'Well yes it's much more than that, but not that many people subscribe to it though'... LOL.
The only point I made, which you seem to be at pains to dispute, is that OpenVPN can't and won't saturate an average gigabit WAN - certainly not efficiently, repeatably and for everyone. WireGuard will. Pick whichever suits, and whichever you prefer; but there's no need to repeat FUD on the back of it.
