The poor industry, self-selecting for high-quality SDKs that macOS won't sign. Wouldn't they be upset if Apple ends up hurting themselves?
As rare as Apple is to admit it, there is this mercurial thing called "competition" that haunts the free market. OpenCL would have had an excellent chance if Apple took it as seriously as Nvidia took CUDA. But they didn't, it was thrown over the fence and expected that everyone else would do the work. While Nvidia was shipping Linux and BSD-native CUDA drivers, Apple was just distributing loose specs and begging the OpenCL working group to stop rewarding their competitor. Not for a lack of funding or motivation, Apple lost because they were butthurt.
OpenCL was DOA the moment Apple stopped treating Nvidia as a proper threat. Everyone else in the industry supported CUDA and was fine with it.
