The ugly answer could be that they don't really care about miner compensation or network security as much as they care about getting their slice (which they would actually be TAKING from the miners).
Now you care about miner compensation and network security? Weren't you the one complaining that you don't want to pay fees because you've bought the right to transact when you bought your coins, etc etc?
High fees = "fuck core devs"
Low fees = "fuck core devs"
For real?
