sure does sound like it, I'd maybe head over to twitter and ask them about why the devices were mentioned etc. I find that social media works wonders when it comes to complaints etc. along with all this GDPR that's going on listing them and reading them sure sounds a bit intrusive.......As for as your devices being connected to the router that has tomato running they should only see that your router is in modem mode, all your devices that are behind tomato will be safe from prying eyes. after all you have to log into the router your self to see them....
On a side note, I ditched "Tomato" and went for merlin as tomato for what ever reason couldn't keep up with the WAN speed of my modem, so after rigorous testing it all came down to the firmware for loss of speeds, I'd never had thought it like as been an avid user of "Tomato" but the good thing about "Merlin" is that it's a lot easier to use, you can set up VPN's for any device on your network to use, so for example I have my mag254 going through a VPN and it will be killed if the vpn drops so no network traffic will be allowed to it, all my other devices running as normal, (you could do this with tomato using a simple script but GUI is easier)I think that's how they block the football using "deep packet inspection" you can check what data is being sent using wireshark, you can see that within packets there's information that reveals certain things about your connections, using a VPN then scrambles all this.....but anyway, that's me blabbering on..so yeah I have the 200 meg connection and have all ways been getting around about 160ish etc. turns out that it was "Tomato" for what ever reason, can't have been the processor etc. as running "merlin" is sweet on my own router.....
