It’s irrelevant to me that the HA mfgs use proprietary OS on their hearing aids because it doesn’t really affect me in anyway.
What’s relevant to me is that their programming softwares are compatible with Microsoft Windows so I can install their programming software on my computer. And they are. I don’t know if their programming software is compatible with iOS so it can be used on the Mac or not, but I don’t have the Mac so I don’t care.
What’s even more relevant to me is that I can use the universal HiPro/Mini Pro to connect their programming software to their hearing aids, so that I don’t have to buy a different and proprietary hardware device specific to their hearing aid brand in order to connect between the programming software and the hearing aids. Sure, they can sell their own hardware (like the wireless FittingLink 3.0 sold by Oticon that works for their OPN hearing aids only), but as long as I can also use a universal hardware like the MiniPro then all is good.
What’s most important to me is that they don’t lock out their hearing aids and not allow anybody but the authorized dealer to do the programming only (like what the Kirkland brand did for the KS5, KS6, hope I got this right because the KS7 and KS8 are not locked out).
Equally important is they make the programming software accessible to the public to download, even if they don’t make that official so they don’t have to provide public support for it.
