Why would there be dedicated servers for macos or linux? The game itself isn't different from windows, and you can play on the same servers as windows based.
Doesn't make sense to keep different servers.
At most, they don't want to support the macos and linux client, not the servers.
If you play Rocket League on macOS or Linux and want a refund for the base game, please follow these steps:
Unfortunately, our macOS and Linux native clients depend on our DX9 implementation for their OpenGL renderer to function. When we stop supporting DX9, those clients stop working. To keep these versions functional, we would need to invest significant additional time and resources in a replacement rendering pipeline such as Metal on macOS or Vulkan/OpenGL4 on Linux. We'd also need to invest perpetual support to ensure new content and releases work as intended on those replacement pipelines.
They offer refunds for base game only.
If you bought anything special, well, you are out of luck (I wonder if this could be a merit for class action lawsuit).
Also they are too lazy to support the clients.
One thing to consider, is that there are vulkan implementations, so dropping DX11 for vulkan, could make their game run on every platform.
Personally I think this is just a "save a few bucks" scenario to make the bosses at epic happy.
