Medtronics' "open source ventilator" bullshit PR

tom66:
Perhaps they are reviewing their code before releasing it.  Checking what licences allow public disclosure for instance.  At a previous employer we wanted to release software from a product as open source but we couldn't get the licence to do so from one of our IP suppliers.

I think the whole point is that with modern 3D printing and CNC machining, you don’t have any tooling to make, which is why numerous people were working on open-source versions.

I can think of two reasons:
1. third-party intellectual property. It’s highly likely that they used third-party software components (that being a very common thing, as tom66 also says above), so they have to secure distribution rights for those components. And even if they didn’t actually use any, they’d still need to review the code to make sure they don’t. Similarly, their CAD drawings might have used 3D models of components provided by the component manufacturers, again requiring legal review to make sure they’re allowed to share them, even if integrated into their own design.
 
2. Finding and/or converting files. Now, I have never done anything CAD (aside from absolute basic PCB design), so this is purely speculation based on how things are in most disciplines, but it’s quite possible that the 15 year old source files needed to be converted to a current format. And that’s assuming they had them sitting on a server ready to go. But it’s very possible they were archived on a tape or hard drive somewhere, and someone had to dig them up. Wouldn’t be the first time that a company had the documentation at hand, but nobody remembered where the engineering files/source code was.

Given that they’d said that they “will” release the files, not “might”, my guess is that they already had them at hand, but had to put them through legal review first.

Again, they didn’t say they “might” release the files, they used the word “will”. Had they failed to do so, the negative press would no doubt have been (justifiably) vicious.

What I don’t understand is your (and then Dave’s) vicious attack on them before even giving them a chance to keep their word, which in the meantime, they have done.

And to be clear, I’m not suggesting that they aren’t doing this for publicity. But as I said before, if what they do ends up being a good thing, who cares if the motivation isn’t selfless? We can approve of this one action without approving of the company’s other behavior.
José.jmaacc:
did you guy took a look at this : https://www.eevblog.com/forum/projects/compatible-microcontroler/
might give you an insight into the medtronics post
I think I need to create another post explaining the idea even further

Medical equipment (especially life support gear), can take years to get properly cerified. Also, the parts used have to be tested and approved already for medical purposes. It's not uncommon to see older parts in medical equipment.
1Ghz:
They released the source code for MCU.

CPU card: ST10F276
Power supply board: PIC18F6622
