Thank you for this "everything for everyone" term. I was not aware of it until now, and it perfectly explains those examples you provided. It also explains why product managers are so focused on "personas". I guess that this, along with push-back on feature creep is a way to combat becoming "everything for everyone". Of course that's true for small-medium companies, after a certain size it seems you welcome becoming "everything for everyone" as you're already entrenched in so many businesses.
