There seems to be a fundamental issue with this model. If it's economically viable for a user to use this service, there's no reason why the company wouldn't just do it themselves. The only exception is the cost of the hardware, but over the long term this is a relatively small factor compared to the cost of electricity and bandwidth. Especially considering that the company could use much more efficient hardware than the typical home or gaming computer.

I understand the 'sharing economy' desire to make use of underutilized resources, but this doesn't seem like an economically feasible way of doing so. The model works for Uber/Lyft: cars are a relatively high upfront cost compared to the cost of gas, but computer hardware is often less expensive upfront than the electricity costs of running it for a year. Additionally, much of the economic value in a service like Uber or Lyft is provided by the driver, not just the use of the car. In this service, the user doesn't provide any value, in fact, they're using up cycles/space that could otherwise be monetized.
