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.
It absolutely does have to do with analytics: in particular, Debian has an opt-in anayltics system called "popcon" which is mentioned in the privacy policy.
Presumably the objective is to have machines that do not connect to the network without at least a human in the loop. This used to be the default, and is still very helpful in a lot of situations. For one, it keeps the noise down when you are trying to debug network issues.
That FSF link relates to their site.
Audacity is an offline non-networked application.
