GZDoom/UZDoom is in a similar grey area, it is a direct continuation of the Doom codebase but they've added so much stuff that it's practically its own distinct engine now.
But it is the same overall code structure, the same game, etc.
All these oss quake engines, are they quake? Ironwail, quakespasm vkQuake?
Seems to be using a dnsft.cloud.zyxel.com certificate. Is this a home router?
