This is correct. DoomRL had been around for over 10 years, but only when the Jupiter Hell kickstarter appeared did it attract any legal attention from Zenimax. I’d guess the issue might have been more with the Doom logo across the main banner of the website, which was similar enough to the original iD software Doom logo that it might well be infringing under trademark law, (i.e. there may be a likelihood of confusion to the consumer that this is a Bethesda / Zenimax product. ) As this logo has now been changed, and the name changed to DRL, with the site and game still up, this seems pretty likely.
