Whatever about this particular instance, there are documented incidents where Microsoft deliberately made things not work; in particular, the Java thing, and the DR-DOS Windows thing (where Windows would run on DR-DOS if it pretended to be MS DOS, but not otherwise).

Since it did not make it into a released version of Windows, it did not actually affect DR-DOS. Still, Novell eventually got an 8-digit settlement out of Microsoft.
