I think it is sad that you feel that way. Minnowbooster is trying to improve the voting bot ecosystem. Steemvoter gives you liberty over your curation.

In the end there is the question if these services are beneficial to the Blockchain. And if they are, we are working hard to make them perfect for you. If they are not, steem has to change, you are welcome that we helped improving it.

And sure, we are closed source because we want our work to be used by us. We see with DrOtto many unstable bidding bots and chaos. And if someone wants more than that, please let them put the work in.

We will over time open source some of our libraries and offer apis for the community. But we won't share our code. And I don't think you can give a good reason for us to do that.

I want to add something: while other bots put their profits into their own pockets we let you use our services and earn. We take a cut of your earnings, so we only earn if you earn. And if you haven't noticed, we are contributing to the discussion.
