Before you argue that ReactOS is merely a free implementation of Win32

    API, let me clarify: if the purpose of ReactOS isn't to run some

    Windows-only software S, then what is the purpose of ReactOS? if S was

    free, it wouldn't be Windows-only as it would have ported to free

    OS's.
I don't object to implementing free software to support APIs that

users use.
There is a lot of non-free software written for the Lose32 API, but

there is also a lot of private (unreleased) software which runs on

that API.  Thus, its use is not only for running proprietary software.

I would ask the developers of platforms that run the Lose32 API

to tell the users that running proprietary Windows apps is not freedom.
