People wouldn’t have booed. This is the same storage pricing as the previous two generations.
So you might be an Apple Fan who happens to be an employee - except you work on idk iMessages or something - you might still be disappointed to see a 1000$ stand, especially from a company you work for.
Given it's a crowded room, I highly doubt employees would be reprimanded for just booing.
I would imagine that would be a pretty big deal with stern words with HR / management or worse if caught
Of course, it's going to be very obvious to most people that the new iPhone 11 is the direct successor to the XR, and the iPhone Pros are the direct successors to the X, XS, and XS Max.
