At my last job, our Director of Operations was responsible for rewriting the company rulebook/handbook. People didn't really know why, since we were a small company and I don't think anyone had ever read the handbook. Obviously, as you can imagine from someone with the title of Director of Operations, no one was asked for input.
A few weeks later, we;re all given copies of the handbook and ordered to sign it. People read the handbook and it was very clear that the new rules were not in line with company culture at all. No drinking in the office when we had multiple beer fridges, stuff about how you can be fired with less notice, etc. Of course, no one in their right mind would agree to an amended rulebook while at a company, especially when they could freely move to another startup.
The thing that amazed me most though, was in our next company meeting, people kept asking the Director of Operations about the rulebook and he finally snapped to say "Look, I made some changes, if you dont like them, its just really not a big deal, I don't think the rulebook actually means anything anyway".
Okay so lets recap. Our director of operations spent months writing a "meaningless" document? Doubtful. If so, why WRITE the document at all? This is the parallel I see here. There was no reason whatsoever to change the terms, yet they had some presumably high priced lawyers rewrite them. Why would they do this? Do we really believe they spent time an effort updating these terms for no reason? To me, this reads as some SERIOUS backpedaling and I would be shocked if they actually didn't intend to use data in the exact way people were upset they would.
