None of the above was an argument about how easy or hard it is to build a service (though Apple has enough resources to build anything they want within the scope that they operate). Given that they are a platform provider, maybe doing the bare minimum to get their own stuff working, but not enough to get any alternatives to work, is a strategic choice on their part. "If Homepod only works with Apple Music, more people will switch" No, a hardware manufacturer has no requirement to support any specific software. An infrastructure provider, however, has (in MY opinion) a requirement to support what they support to an equal degree, or it amounts to… market manipulation? Something not quite fair, some kind of abuse of power which is to the detriment of all other participants in the market, customers and companies alike. Obviously, America as of today disagrees, seeing as net neutrality is not held in very high regard. I look forward to roads that only support Fords, water pipes that only support Nestlé water, and stairs that only support Nike shoes.
