I can’t tell if you seriously think a random person writing code in their basement is equivalent to a company that has access to API docs, design specs, actual test hardware, the expertise of a ton of engineers that have worked on the project and understand how it can go wrong, not to mention all the regulations and verifications they’re subject to.

But if you do then wow. That really puts in perspective the kind of people that use hacker news. I’m gonna be more selective about who I bother replying to going forward.

Tested how? With 100% "unit test" coverage? I can certainly see how a random person on the internet might be highly motivated and actually talented enough to contribute to these sorts of projects. But they don't have the budget and resources that commercial entities have. They don't have the same due diligence requirements. They don't have the same liability. If I use a commercial device unaltered, it's the company's fault if the device fucks up or is defective and causes harm. If I install random internet software on my medical device and it fucks up and causes harm, it's my fault.

I say this as someone who might modify my own medical devices because I'm so fucking jaded over the capitalist march towards enshitification and maximizing profit over human lives. There is simply no way random folks on the internet can test these types of systems to any reliable degree. It requires rigorous testing across hundreds to thousands of test cases. They at best can give you the recipe that works well for them and the few people that have voluntarily tried their version. That doesn't scale and certainly isn't any safer than corporate solutions.
