I have many nerdy friends who have been Linux users for ages. But most of them don’t know such a thing as Openwrt exists or have never bothered to give it a try. It’s a very fun piece of software to play with and can be extremely useful for routing traffic. Wondering why it isn’t more popular/widely used.
I used it in the past, and it is great.
Nowadays, I bought a mid price router from a well known brand, and seriously: The router works, has all features I need (even WireGuard OOTB) and for now I see no reason to replace the provided firmware with OpenWRT. YOLO!
