If all you are offering with your native desktop framework is a dumbed-down experience, because it has to also run on tablets and phones and TVs and game consoles and smart refrigerators, then you quickly get to a place where there are few advantages in going native over shipping a webapp in a Chrome wrapper.

Windows 8 was a catastrophic failure, and Apple seems to be leaning into the same failed philosophy now.
