Technically nVidia chose that fight, not Linux users.

nVidia is chocked full of proprietary implementations meant to bog down competition, for example all CUDA technology including translation layers are technically illegal to even look at without nVidia proprietary drivers.

This already described that Linux user started that fight, and they chose it.

But they cannot do anything than using the proprietary drivers, screaming about moral, propagating GNUism.

But they never write their own drivers for many hardwares like the OpenBSD project do. OpenBSD convinced many manufacture to release documentation.
