Companies "change direction" all the time, I wouldn't call it lying, You hide behind a concept that if a company says one thing, they'll never ever go back on that. I wouldn't take an employee's comment as gospel, it can and will change as the market conditions change.
Here's some nice quips about from Steve Jobs
(link) where he's basically saying apple won't do x, y or z and yet they do ¯\_(ツ)_/¯
$$ pure and simple
Agreed, and they've been moving to locking the Macs down prior to ARM. Try to install Linux on the internal drive and you'll see you can't.
And its worth the paper its written on.
To some degree, yes of course. But at the end of the day, where will Mac users go? Just look at the typical mac user here, and many (most?) hate windows. So many of them will unlikely switch, even after much grousing. Looking at typical consumers, who show up at an apple store to buy their son/daughter a computer - will they care if have to get their apps through the app store, no.
Now that's your opinion and not Apple's official stance
Please explain? Xcode can (is?) in the app store, and they'll be able to "install" apps they're working on just like they do on iOS devices prior to getting approved in the app store.
