While I don't agree with it, I see in your FAQs:
Am I charged while my Droplet is in a powered-off state?
Yes. Your diskspace, CPU, RAM, and IP address are all reserved while your Droplet is powered off. If you want to save a Droplet for future use take a snapshot of it and then destroy it. You'll be able to create a new Droplet from the snapshot image anytime to bring it back online.
I believe you are only following what others are doing instead of innovating here. This is a HUGE pain to app developers who need on-demand servers and don't want to spin up/down every time. For example, if I want to host development or staging websites here, I either have to pay for 24x7 service or destroy and then reupload all my files/databases. Instead of taking the high road ('everyone else does it this way') come up with a competitive differentiator. You could put the hardware in a "lights on" state, release the IP, etc. and charge a fraction of the cost. I'm sure this could be done with enough research.
