Why are you folks even here posting? This is just a hate all things Microsoft rag. I work for Microsoft vendors all the time on campus and have had my fair share of exposure to the folks in the Windows Phone group. If you think that the possibility that certain Lumia or Windows 8+ phones won't be able to update to 10 because Microsoft wants to sell you a new Lumia you are nuts. They want as many happy people as they can possibly make happy. They want as many people using 10 on all of their devices as they can muster.
Get a life folks.
