How do I receive a chromecast with that SDK, please?
The point is not about sending, but about receiving, as was possible with miracast, and which would have made the fire stick a killer product (by having immediate compatibility with all Google apps' casting feature)
Your argument that Cast is hard on unsupported platforms is irrelevant. They are, by definition, unsupported, and Google is under no obligation to support them.
Google provides an SDK that people are free to use on the platforms Google chooses to support.
