Most concepts in Metal build on concepts learned from GL/DX11 and carry on to Vulkan/DX12. This is better than starting directly in Vulkan/DX12, quickly getting overwhelmed and giving up. Plus it makes the step from GL/DX11 easier. I bought an iPad last month just so I can play with Metal on an actual iOS device at home :) I don't think hobbyists care about market share that much; they want to get hands-on and learn, and Metal is a rather fun API to work with.
