I think the worst company in the world for the United States is Apple. I would not be surprised if Apple is suppressing program designers from making applications for Windows Phone. Keep in mind Apple owns the American market because Americans are too stupid to realize they are not an American company anymore, they've moved millions of jobs out of the United States and they pay relatively no taxes here.
Microsoft, is a big threat to Apple because of Microsoft Office. There is such a great link that could be had between phone and computer and many businesses would not use or even cannot use Apple computers because the software is not there. So Apple wants to bury Microsoft in this arena as this arena may end up controlling both markets business computers and phones.
It is my opinion that Apple pays very logical voices in the United States to not say anything about what Apple has done, expatriating from the United States. Sure, their office is in Cupertino but nothing else is and no tax is being paid on the hundreds of billions of dollars of sales, like most people believe it is. Al Gore is on Apple's board of directors. Bernie Sanders hasn't said a word about Apple when he named the 18 worst companies and Robert Reich who I thought was a good voice for labor and economics, also not a word about what Apple has done.
What is Satya Nadella doing about this. If these logical voices don't say anything, perhaps commercials should be targeted at Apple and what it has done. Perhaps Microsoft would love to do that too but as of now Microsoft is still an American company. Apple is not. So I believe that is why those who write apps are staying away from Windows Phone. This could be a restraint of trade issue if they are pressured to ignore Windows Phone.
