It is exactly because of the hardware: Itaniums are pretty much unobtainable these days. This makes supporting software for these machines difficult and very expensive. This is the natural consequence of the manufacturer also having obsoleted it. Even quite outdated PC is trivial to obtain and support in comparison. Also for Amigas and C64s software maintenance is vastly easier since there are practical emulators.
