Why are Scrum and Kanban sometimes discussed as if they are opposite?

I see a lot of articles on the internet with titles like "Choosing Scrum vs Kanban for Your Team".

This sounds extremely strange to me. Scrum usually means working in sprints, having meetings, a product owner and a scrum master. Kanban usually means having a board and moving tasks through it in a linear fashion.

Why would anyone contrapose them and choose one instead of the other? In fact, I've never worked in a company that wouldn't do both: almost every team I worked with had sprints, daily meetings, as well as using a kanan board (usually Jira).

Am I misunderstanding the meaning of these terms? Or are the articles that contrapose them just poorly written?

Thanks!
