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.
Yup. Running it on my home router, right now. It is awesome. A tiny, stripped down OS that you can install minimal packages on. Like a VPN client, or ad-blockers. If your router is compatible, I cannot suggest it enough.
Also, my router's manufacturer had the gall to ask (force) me to sign up and get an ID with them in order to get to the back-end of my own router. Jesus Christ, privacy red flag much?
I could not install OpenWRT fast enough.
