Strong points. But from a usability perspective, Bootstrap would be much more significant if it were opinionated about interactions instead of just gradients, whitespace, and CTA placement. The examples list of beautiful, usable, and identifiable products and services is long. People learn new patterns quickly - you just have to do a decent job designing the pattern. Bootstrap's "non-coercive standards" are really just CSS shorthand for an approximation of Apple's successful, so-simple-it-feels-generic, already-easy-to-copy example. Anyone who never invested in a brand or consistent visual language before (and therefore simply wouldn't have a brand or consistent visual language) now just piggybacks Apple's aesthetic. Bootstrap is a small step further on the already well-worth path.
