my LG TV was up to date but I still managed to root it just recently, via this method: https://github.com/throwaway96/dejavuln-autoroot
it's well worth it - rebinding the remote alone is sweet AF, plus the ad-free and sponsor-blocking YouTube is great
I have a few personal domains registered with Njalla and have for years with no issues. They're not hosting anything shadier than a Jellyfin login (on a non-Njalla server) - and so I'm not worried about getting denied access. And I like not having my real details in the WHOIS.
