IMO, it shows security is not a priority for them. Just because you’re on LAN it doesn’t mean encryption is insignificant. There also isn’t really “LAN” there are just networks, so this necessitates using some sort of server even in the case where you have an IPv6 or IPv4 address that would otherwise allow you to directly connect to your peer.
I’m really glad AT&T and Verizon decided to step in and start competing. At least in my area it’s changed everything, Spectrum (formerly the only cable provider) is now offering much more competitive pricing and better service (though AT&T has earned some loyalty because the fiber and symmetric speeds have been really great.
Following the Biden admin pricing transparency regulations I was able to get a better price as well.
