I was reading on reddit that you buy licenses for individual nodes, so that means that if I have a docker cluster of three master nodes, and I have platinium licenses for only 2 nodes, my cluster will still have his license expired?, still cant use machine learning?, eventually I will have to drop one node?

That's correct, if you have a three node cluster then you need a three-node license.
