They did, and they still have the rpi foundation with that goal, as well as the for-profit subsidiary.
It's a flaw with effective altriusm-- you have a goal of fixing some large scale problem and at some point you realize you need large amounts of capital to expand your impact. But the interim period you are just going to be amassing wealth with this idea of doing good. And even then, you may never reach a point where you feel like you earned enough to solve your problem.

Now I'm not saying that rpi foundation hasn't done good in the world. I'm just saying that they did start off with a lofty goal and it is clear that they are wanting to expand and make more money. Maybe this means someday they'll be able to do even greater things through the rpi foundation.... but I'm not optimistic
