That's so generic - "basic CRUD(website)". It's ridiculous. You're a UI developer, of course you're going to design a UI for CRUD functionality in the next five years.
My problem with NDAs is that even if the company decides to pivot and abandon the "idea" altogether, you are still bound by the NDA for that time frame. It restricts creativity. Shows a lack of trust. Etc. In my experience, those who have the worst ideas, who have no understanding of what it takes to execute said idea, are generally the ones who shove an NDA in my face before I even say, "Hello."
