Built a userscript that checks the publisher on Steam and GOG game pages against the Stop Killing Games Dead Game List. If the publisher has shut down always-online titles before, you get an amber banner with the reason.
Currently flags 16 publishers: Ubisoft, EA, Microsoft/Activision, Warner Bros, Bandai Namco, Sony, Square Enix, 2K, NCSoft, SEGA, Capcom, Rovio, Gameloft, NetEase, Nexon, Atari.
Open source, no tracking, dismissible banner.
