Chuckle. Of course the vendors of non-free software charge unfair competition when governments participate in sharing the load of producing software. That cuts them out of the picture unless they also work for a living… Get a clue. The world does not owe you a living simply because you know and love non-free software. The world can and does produce its own software cooperatively at a fraction of the cost.
I recommend everyone check out truly Free Software by installing and using Debian GNU/Linux. It’s a cooperative project of the world and it allows you to install software without a purchase-order or contract and you can update all your software, applications and OS, with a single command. Of course vendors of non-free software want you to do it their way with each application and the OS needing a separate means of updating and requiring a separate purchase-order and contract with onerous terms for each package. That inefficient system allows them to make tons of money without doing any work at all…
