Sure it's not "the norm" but personally I run a Poudriere[0] server and build all my own software packages. One server syncs the FreeBSD Ports collection and downloads the needed software source distfiles, but then none of my other machines/jails are allowed to install software from anywhere outside my own network. A lot of them don't get any Internet access at all.
That still has nothing to do with in-app analytics though.
