Not sure this is a good thing since The Dreamcast Junkyard got a cease and desist from Sega after their Ultimate Collector's Guidebook got featured on Sega Central.
Well it was moreover that they were selling something with their trademarks and copyrights all over it, and they had to send them the C&D to protect their trademarks/copyrights. This is why a few years back Bethesda sent Mojang a C&D over that game "Scrolls". They knew there would be backlash but if you don't protect your trademarks/copyrights you essentially lose them
I'm not smart I heard that on Extra Credits and it sounded pretty on point
But point being nobody is selling the servers or using trademarks
