I don't really care who's to blame (I'd guess I'd blame both
the Linux distros and the Linux application developers), but
the move to put everything in /usr/include and /usr/lib annoys
the heck out of me. It blurs the line between the base OS and
installed 3rd party software. Perhaps that's because Linux is
really just a kernel, and to the distributors - most, if not
all, of their software is 3rd-party.

It's really nice to be able to install 3rd-party software
so that it doesn't affect the base OS. On FreeBSD, it's
easy enough just to 'rm -rf /usr/local' and start fresh
without having to worry about screwing up the base OS.
