Problem is that diverse doesn't really say anything, it is just a positive word. Diversity is often a bad thing, you don't want to have to build a diverse set of services for one functionality etc. Diversifying your income streams is good, but also not good since it dilutes efforts, you know there is also the "focus on your core business" mantra that goes the exact opposite.
Edit: For example, can you explain what "diverse work environment" means? Do they have no desk standards so that desks don't fit neatly together? Do they lack AC so that you get a diverse temperature over the year? Inclusive work environment would have said more, but diverse? Whatever positive meaning you attribute to it comes from your own imagination, that is the main selling point of these slogans. You don't promise anything but people still feel you said something good.
