I just wrote DOS as I always abbreviated MS-DOS as DOS.
DR-DOS actually came with the first PC I bought and it was for all effects a MS-DOS clone, hence a DOS clone, like PC-DOS from IBM and a few others on those days.

Under this argumentation GNU/Linux or even OS X is a UNIX clone and both should be abbreviated to UNIX (or UN*X to avoid trademark violations ;-) ). Indeed both originate from UNIX clones - but then new features were added that made them better than the original in a sense. The same happened to DR-DOS. Read DR-DOS' wikipedia article to read about features that DR-DOS added over Microsoft's original.

But then add Glide (DOS), please. :-)
I remember playing Screamer 2 with that. I think my brother still has his 3dfx cards lying around (Voodoo Dragon, Banshee etc.)
Happy times. The music in Screamer 1 was better though, more noodly guitar music in the style of Satriani.
I left it out on purpose, because DOS was a Microsoft platform as well.
MS-DOS was a Microsoft platform, but not DOS itself:
Also Glide was not a Microsoft API.

Did you failed to read I was a DR-DOS user?
I use computers since the early 80's.
I was a DR-DOS user, too (Novell DOS 7).
But I believe Glide wasn't a Microsoft API, so the example is still fine to defend your case.
