At least make it last a year, the current limits are completely stupid.
This is so unbelievably retarded.
What I have said is stupid is: your attempt to use that software as an argument in favor of loosening Apple's restrictions on iOS applications. The apps in question are such a legal nightmare that they're not available in any major app store, for iOS or Android. No business with a competent legal department would want to be directly involved with those software projects, unless they were planning to incorporate them into their own product and get it certified by regulators like the FDA. If Apple or any other company in a similar situation decided to open up their platform and even mentioned that one of the benefits of that change was to enable this DIY medical device use case, that would probably put them at substantial legal risk.
Regardless of how useful you find such software, you're not going to get a corporation on board by drawing their attention to such a big legal risk. You're also unlikely to win over government regulators, since they're likely to be of the opinion that medical devices should be regulated.
You've identified a reason why some customers may want Apple to change their strategy, but you've completely failed to provide a reason why Apple would want to change, or why a government would want to force Apple to change.
