This shit where they block of the defaults:write option until the next OS version if ever or there's a blowup in the media/scrutiny or they pull the bullshit SIP card when nobody fucking needs AppleTV or AppleNews or iMessage etc on their Mac, yeah. I wish MacOS would get to Microsoft levels of uniquity so various Justice Departments around the world could cut the cord on this horseshit.
