DM (Dungeon Master) is a registered trademark by the rights holders of Dungeons and Dragons, that’s why Game Master (GM) is used as a generic term free of the fear to get the Pinkerton’s send at your door
I don’t think DM is a trademark, but if you have other information feel free to provide it. Looking through older discussion forums on this topic, the only semi-definitive answer I’ve found is in this 2021 thread where somebody referred to a now-defunct US gov’t trademark search link, where they said they found a lot of "DM"s registered but none related to D&D. I’m inclined to believe it was a working link at that time and they weren’t just making shit up.
Personally I use the term DM because I’ve mostly played D&D, so to me it’s more natural.

“DM” is not a trademarked term, because it’s a pair of letters. “Dungeon Master” is absolutely a trademarked term, though, and has been since the TSR days.
Thank you for this information, I have added it to my original comment.
Some other games use other terms. Like wod uses “storyteller”.
GM is the generic term
