I mostly agree although I also think a lot of businesses think they are a lot snowflake-ier than they actually are.

But in my experience, smaller businesses can actually be worse offenders in this regard. Large enterprises actually do have a lot of complex needs and even relatively small changes affect a lot of people. But I've had someone at a very small company argue with me that they needed their own Exchange server because Gmail (at the time) didn't have some features like sub-labels/folders that they were used to.
