Thanks for bringing those up. We're certainly aware of Quirk and the story, although we haven't as yet talked to the founders in person. Their story is very relevant to this discussion.

The points about sustainability of business model are very relevant ones, which is why we have a long term aim of building software as a medical device, which is potentially distributable / reimbursable by healthcare systems / insurance. This also opens up potentially different payment models, which can be more sustainable.
