>You still use games from big corporations, even if they're cracked.
This misses the point entirely. Running a server for a 14 year old version of cracked Minecraft or liberated TF2 from 2008 isn't "using corporate infrastructure" - it's using software that happens to have been made by corporations, but completely divorced from their control systems.
No telemetry. No accounts. No DRM. No forced updates. No data collection. The corporate surveillance apparatus gets exactly $0 and zero data points from our servers.
By this logic, using a ThinkPad is "supporting IBM/Lenovo" and running Linux is "supporting whatever corporate contributors touched the kernel." It's ideological purity to the point of uselessness.
The FOSS game suggestions are valid though. We'll run that poll and see what people actually want to play.
If you want to play Hedgewars instead of Minecraft, great. If you want to play liberated Minecraft without Microsoft getting a cent or a data point, also great. Both are infinitely better than paying for the game and logging into your Microsoft account.
