I think it's an overused concept because it's exemplary of a larger cultural issue. People praise 'openness' and optionality, (not just in software tools), and are skeptical about any form of commitment simply because it closes off some paths. In programming it comes up a lot with opinionated programming languages, IDEs etc. Environments like Emacs with their idiosyncrasies and age tend to be disregarded because they aren't all things to all people.
