I think you put too much attention to botnet miner because hanlab user is responsible for 41% of total hashrate in last 24 hrs. All remaining users (approx 176) on my pool generated 15% of blocks in last day. The real problem is that there is not so many miners in total to even the hashrate distribution.
The problem is: ordinary miners have to pay for electricity and so on, but hanlab not.
So ordinary miners just can't compete with bonnet(-s) and leave Dash. It isn't normal situation. And as we can't setup many "competing botnets" - it is better to kill this existing one to return to normal miners competition.
