It's true that users won't be annoyed by a standard Bootstrap site, and in fact is preferable to many high traffic websites that just look absolutely terrible. The point is, however, that it doesn't give your website/business/product very strong branding if your website looks just like 10 other ones someone has seen. It's not a problem with usability so much as it is with creating something beautiful that actually represents the brand and evokes the right emotions. Stock Bootstrap doesn't do that. Totally fine for blogs, presenting a weekend project, and many other use cases, but there are also many instances when it would be a very poor decision.
