> I guess 70 years ago companies were far more open with sharing such things
Thanks for this post I upvoted a few of your comments. That said being a bit older and in business for many years (since college) I think it's the opposite actually. When I was 'growing up' in business you didn't share your secrets or give out any information whatever that would be helpful to your competition unless it was disinformation. So this didn't start with Steve Jobs and Apple it was pretty much status quo for all business. The internet changed that and I think at least one of the reasons was the involvement of academics who were more used to sharing what they knew.
There was a time when all electronics had detailed service manuals with discussion of theory of operation and troubleshooting checklists. Early PCs came with ROM listings. The techo-secrecy culture set in during the 90's.
