I think the author hits some of the major generic reasons to not use any framework: 1. Steep learning curve 2. Technical debt from learning curve 3. Technical debt from code bloat 3. Increased difficulty implementing unique features But there are others that are even more important. One is that frameworks are often used to avoid learning the underlying technology that is more powerful, universal, and portable. It is falsely believed that time can be saved learning a framework instead of core coding skills. I have not seen any evidence that this is true, but like all snake oil, people believe because they want it to be true.
