Earlier quoted context omitted.
No, but it is no longer supported by Microsoft so it is abandonware. It is still closed source and piracy to copy without permission but Microsoft does not care about it because it is too old to sue over.
They've been known to send C&Ds to various sites that host old versions like this. "no longer supported" is a flimsy argument for abandonware anyway. by that reasoning, Windows 7 is abandonware and it still runs basically every Windows program ever.
While those self imposed criteria may be regarded as acts of self-preservation, I get the impression that some of the people who run these sites are more interested in software preservation. (In earlier times, many sites actively sought out permission to post software but it sounds like that became all but impossible for various reasons.)
