Education is their mission, but people say this in defense of every product they release these days. The primary enabler of the mission is not the educational sales themselves, it's the sales for embedded or general tinkering use.
I think what people really overlook is how much brand recognition and mindshare "Raspberry Pi" has from the earlier products. That carries a very long way, but if none of the new products are supposed to scratch that same market itch then there will eventually be a problem. It reminds me a bit of folks who felt Mozilla should only care about the overall mission for the web instead of making sure Firefox grows to continue supporting that mission. They couldn't rest on their laurels forever to only do the mission either, and are in a tough spot for it.
