When the people you are hiring are an external contractor, that probably counts as distribution though.
If you send them the software, they reverse engineer it and fix bugs that's not distribution.
If you send it to them, they fix bugs and then start using it themselves that is distribution.
However, when the organization transfers copies to other organizations or individuals, that is distribution. In particular, providing copies to contractors for use off-site is distribution.

So whether the FSF calls something distribution in their own FAQ is irrelevant, unless the FSF is your lawyer and giving you legal advice.
