I feel sorry for the people whose office is behind that huge banner...
They will undoubtedly sue Apple, dropping the stock price and bringing out the " fire Tim Cook" crowd in all their glory!
I've been in buildings with banners like these before and usually these things are kind of see-through from the inside, though they look like solid material from outside they're actually perforated like a mesh to allow seeing out... can't speak for this one though specifically, of course.
