Hi Noam, Your company's attitude is unfortunate, short-sighted, but also typical. This matter is not about the quality of your graphs or analysis algorithms. Yes, of course you want to make the product easy to use and accurate for users. All of your customers want that as well. Making the product easy to use and accurate is not incompatible with also offering a way to get the raw data. By blocking access to the data, you are missing a business opportunity. Your software is free anyway; therefore, what should matter to your company is selling as much hardware as you can. If you expand the potential uses of the device by gaining the interest of more users, you will sell more hardware. Why not offer a simple raw data output in some text format (e.g., simple CSV) as an advanced option for those people who are interested in exploring further? We're not asking for you to disclose the analysis algorithms or open-source your software; you can keep those closed. You have a brilliant device and it lends itself to creative applications, so let the tinkerers explore. Isn't it obvious that the more people want to explore using the device, the more devices you will sell? Bonus: you get an additional P.R. opportunity by touting how you listen to customer requests.
