Duo is greedy!

I gave money to encourage Duolingo. And I am sure a lot of people did it. But it is not enough for them! They want more! So they purposefully changed the rules and how duo works to force people to give them money! Now they started Duolingo plus for 12.99$/month! They should charge much less! They are already gaining a lot of money! But Duo is greedy! Duolingo was great! Now it is sick!
