Bootstrap is a godsend for the corporate world and the vast majority of industry software shops that don't have huge levels public web exposure. Most of these places don't have the resources to hire dedicated UI specialists with the hottest CSS 3.0 skills, are still forced with IE6 somehow, and end up being designed by devs who liberally use nested tables and iframes like it's 1999. I assume this dislike for bootstrap comes from those who believe it wants to compete as the de facto UI for anything of large scale or designed for instant sex appeal. Anything on that level will have their CSS highly customized and optimized by their specialized UI staff. I can also assure you, CSS and choice of UI framework is the absolute least of your priorities over business development, marketing, revenue generation, and security holes. Get the product out the door, and see if people actually want it before you worry about them inspecting your page source and find that you've used bootstrap.
