This is completely the opposite of my experience at a very large global
financial company. They are extremely concerned with staying current,
and in fact audit regulations require it for any software not written
in-house. If they were still running Oracle 8, for example, they would
fail internal audit precisely because it is no longer a supported Oracle
version, and thus security and such patches are no longer available.
The same would go for operating system patches, firmware, whatever. The
release cycle does tend to be slower (from quarterly to yearly) for,
say, things like AIX or z/OS or DB2, but updates are coming out
routinely [including security and bug fixes, as well as feature
additions], and in my experience these shops are definitely keeping up.
The only places I've had direct experience with that tend to run very
old versions of things are doing so for all the wrong reasons. They
seem to be learning, albeit slowly and painfully, the demerits of not
