I'd argue SteamOS has done a lot for Wine. Nowadays, a huge chunk of Windows games works on Linux seamlessly. If governments start mandating Linux, then every company working with the government will be forced to be Linux compatible as well. That means having file formats that work natively on Linux, drivers, and all the other things that come with mainstream use.

What is "The Year of the Linux Desktop" exactly? How do we measure this exactly and what does that even mean? (I use that phrase for memes usually.)
