A bunch of hardware is now losing maintainers because Intel is laying people off because of its financial woes. Fewer people are being paid to package software as priorities change with other vendors. Half of Red Hat's QA team moved to other things, and there's at least a temporary gap in Fedora testing due to it. Etc.
The corollary to the random person in Nebraska is the person employed by $bigco that eventually retires, quits, or is laid off and another hole needs to be filled.
