Because the tokens that are not pay to bounty hunters will be turned to developers wallets. Then they will have more money, because they are real shits in cryptocurrency space and they don't care about market, community, their project, products, development. They only care about money in their wallets. That's all.
I don't think they're that malicious.
They're mostly incompetent.
Failing to pay your bounty hunters is kinda like investing in NEGATIVE PR for your project.
No-one benefits from this, except the wider community, which can clearly see that a project is garbage.
