No idea. I opted in through the beta options and disabled it from there as well (at the bottom of the preference screen). I still have the beta option enabled though.
The couple I remember reading that have been deleted were about how the CEO and the COO park their Ferraris/crazy racecar sports car in 2 designated spaces directly in the front entryway (like literally exactly in front foyer the building) whereas the actual handicapped spots were about 150 yards away down the parking lot away from the entry of the building compared to the CEO/COO spaces.
There were also complaints about ridiculously high security to the point where people didn't even know their own exact job descriptions/workflows because of "competitive secrets" and that they couldn't talk to people working in other departments due to paranoia/culture of fear.
Finally there were a couple about how they interview and act like your job will be at the fancy building on Sand Hill near Stanford but really the bulk of the employees are relegated to annexed buildings far away in EPA or in Mountain View, yet they don't tell them this until their start date - during all their onsite interviews up through the offer letter it seems like they'd be working at the HQ on Sand Hill.
