Well yes, but that's a pretty special case. Those running such ancient hardware keep their own software and patches, and you don't see many software vendors supporting them unless their are being very well paid. OpenBSD itself does not support even VAX anymore, and developers felt pretty happy when they finally deleted large portions of specific code. Ubuntu is talking about dropping i386. Given enough time, the burden of supporting old hardware outweight the benefits for pretty much everybody, so it makes sense that it should fall on the shoulders of those who decided keeping the old hardware was a good idea.
