I understand why, technically speaking, glibc doesn't support static linking (and I also think that it's bad design). What I don't understand is how this makes it "incompatible with anything". The glibc-specific APIs, sure, they do - to the extent the apps actually use them (which, judging by the intersection of e.g. Debian and FreeBSD package repos, is not exactly common). But how does denying the ability to link statically promote this goal?
