Earlier quoted context omitted.
The basic version of Whist (with limited cloud tabs usage), will be free, forever. For full cloud tabs support, we'll be charging a subscription fee as an add-on on top of the browser. We're still figuring out exactly what the pricing tiers will be, but we expect it to be in the 10-15$ range.
I would feel way more comfortable with a paid application. Otherwise, how are you paying for the cloud compute time? Also, where is the company based and who are the funders?
Charging a subscription fee is the primary way for which we would pay for cloud compute time -- but we're thinking there will be a version of Whist which will have very limited amount of compute time and be free (a sort of free trial if you will)
