This article mix a bit of everything. There are no rules to create a killer product. That's the whole purpose of the product management domain.

Regarding opinionated software they are great at creating alignment between people who have different background. But are not really good for complex use case. Look at excel, nobody is going to say that this is not a killer product but still being not opinionated at all. On the other side Github is a killer product and very opinionated.

But anything is possible, look I'm currently building an alternative to Confluence. You could say that knowledge management is a perfect area for opinionated software, so why is Notion (not opinionated) the killer product in that domain now ?
