The Raspberry Pi foundation is not a computer company, they are an educational charity that just happens to also make a computer. Their primary work is in pedagogy resources, research, and support. A Raspberry Pi has more educational resources, because literally that is the primary work of the company that makes it. They have a full CS curriculum for ages 5-19. The entire reason it exists is as an educational tool. Their mission statement doesn't even mention making a computer -- they simply do that to support their primary education work.

It wasn't until later that hobbyists and commercial interests also started using Raspberry Pis for things outside of the classroom. But that's where they came from.
