Swiftfin isn’t perfect, but Is pretty good on AppleTV.
Quad9, DNS.Watch, OpenDNS
Three good alternatives.
They are the ones mostly developing all the foss bridges (for Signal,Telegram etc).
Not really mad that they are keeping some of their product closed.
Still giving us selfhosting folks the tools we need.
