Yes, these drivers are likely to be Windows only. Linux users will probably be left unsupported. I've seen posts on reddit from players who say they have already been banned for tampering with the game. All they did was log into it from Linux without the third party anti-cheating software running.

Lack of Linux compatibility means people have to choose between playing the games they enjoy and running a free operating system. They will indirectly sacrifice their privacy and freedom in order to get access to the games.

There's also the fact that, just like the hardware manufacturers, the company will eventually stop supporting old version of its proprietary drivers. Eventually, they will no longer run even in newer versions of Windows. The games may be rendered unplayable due to lack of maintenance. Installing old versions of user space libraries like DirectX isn't going to help in this case.
