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 use dd-wrt a little bit, then tomato and variant (usb, toastman, fresh) then Merlin for maybe 5 years now.
Broadcom routers are mostly not openwrt compatible
