Microsoft Corp responded to Wabi saying that it is proof that Windows NT is becoming a real threat to the Unix market. Wabi is just a temporary distraction to comfort worried Unix users. It will be an expensive detour for users – it is much simpler either to buy Windows now, or wait for Windows NT, which promises links into Unix. Furthermore, if Sun Microsystems Inc has infringed its property rights, an issue yet unproven, Microsoft says that it will start legal proceedings. The company, which has no plan to put the Windows Application Programming Interface into the public domain, characterises the Public Windows Interface initiative as farcical. Why should users want Windows to be put into the hands of novices? The companies involved have no technical experience of Windows and couldn’t guarantee its future.
