It even kind of irks me when people talk about “Bethesda” when it's really “Microsoft Corporation presents Microsoft Gaming presents Zenimax Media presents Bethesda Softworks presents Bethesda Game Studios”.
Not picking on you in particular since the same thing happens with iD Software, Github, NPM, and many many more. I feel like there's a collective lack of straightforward language to discuss the influence of this kind of corporate structure. Falling back to the singular-subsidiary name with the rest unspoken is probably exactly what they want.
