Rocket League has been going through many changes, following the purchase of developer Psyonix by Epic Games. The latest announcement for the game doesn't alter lootboxes or attempt to change storefronts this time, however. Citing "adapting [the game] to use new technologies" and difficulties in supporting multiple platforms on PC, Psyonix has decided to end macOS and Linux support for Rocket League this year. Soon, a patch will go live for the Steam version of the game, disabling online features for the game for those not on Windows. Matchmaking, private matches, tournaments, Rocket Pass, item shop, in-game events. and anything requiring online connections will no longer work, and will be exclusive to the Windows version of Rocket League. Local/offline features will still work as expected, though, with local co-op/versus, car customization, and old Steam workshop maps still being usable. This change is expected to take place in early March.

We want Rocket League to be the best experience possible for all our players. This includes adapting to use new technologies. This has made it more difficult to support macOS and Linux (SteamOS). Because of this, we will have a final patch for these versions in early March.

The macOS and Linux (SteamOS) versions will no longer be updated or supported after the final patch. You will still be able to download and install these versions, but some features will not function as expected.

UPDATE: Psyonix's community manager has released a statement regarding the issue, along with some updates on refunding.

Regarding our decision to end support for macOS and Linux:
Rocket League is an evolving game, and part of that evolution is keeping our game client up to date with modern features. As part of that evolution, we'll be updating our Windows version from 32-bit to 64-bit later this year, as well as updating to DirectX 11 from DirectX 9.
...
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.

The number of active players on macOS and Linux combined represents less than 0.3% of our active player base. Given that, we cannot justify the additional and ongoing investment in developing native clients for those platforms, especially when viable workarounds exist like Bootcamp or Wine to keep those users playing.

It's still a shitty thing to do.
