People booed 2 years ago when they announced the price and they booed this year when they announced the Mac Pro pricing, You could hear it when they announced that expensive stand so that’s clearly not true.
The is pure speculation, but I think it could still hold true. Consider that many Apple employees aren't involved with every project, and Apple is known to heavily segment their developers.
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.
