Opinionated products
An opinionated product is one that takes a stance on how it should be used. It's not a tool for everyone, but for a specific type of user who wants to accomplish a specific goal. Instead of targeting anyone to use it, it's designed so only certain users will want to use it in certain ways.
For example, rather than providing lots of options for how to do things and how the interface looks, an opinionated product will have its own preferred methods and styles. Rather than giving you multiple ways to accomplish something, an opinionated product will force you to do things its way. This makes life easier for users who don't need flexibility; they just need something that works well right out of the box without having to set up their own infrastructure or customize anything themselves.
I see non-opinionated products as restaurants that have different type of food on their list. It can suit you in some cases but it generally means that they don't have a single thing where they're excellent at. When you don't know what to choose always prefers a place where there's not much choice, it also means that it'll will be easier for you too choose.
