No, they were not
forced. It was a
choice. They built the

TV4 so that it was still pretty much locked to 1080p MAX while simultaneously rolling out new hardware in other Apple devices that could both shoot and play 4K... and touted that 4K ability in the spin to help sell that other hardware.
Correct. Certainly Apple is smart enough and resourceful enough to roll out a 4K STB that could play 4K YEARS AGO. Instead, they clung to 1080p until pretty much everyone else had gone 4K. They did the same when

TVs clung to 720p as "HD" when pretty much everyone else had gone 1080p.
For a couple of years now, we've been able to shoot 4K on our Apple devices, edit 4K on our Apple Macs in Apple video software, export 4K video to an Apple Quicktime file (MP4), store those files in Apple iTunes where they will play just fine. The one "just works" link between iTunes and a 4K television is this Apple product clinging to a standard Apple rolled out way back in 2012.
Nevertheless, I'm completely ready to buy several 4K

TVs as soon as they are released. It's frustrating how slow Apple can move on stuff like this but welcomed once that finally show up.
