I see many projects that brings value for Hive being funded. I also see some that I don't think should be funded and are currently funded. Some people have different opinion then me. That's why we vote!
The beauty of decentralization! DHF might not be perfect, but it works.
If you don't like it, you should make your own proposal to change and let the community vote.
Maybe it should be user that "learn" how to vote so that these projects dont die the day DHF stop funding them
