You have a lot of faith in how technically versed the law and courts are on these topics - because they sure haven't kept up with the times. And even if they were willing to split hairs over these technical details:
No civilian will agree with you that just because technically you could slip through several doors that happened to be not locked and got helpful advice from a neighbor, it doesn't mean that whatever you found behind those doors was "public" just because you didn't have to pick locks. Or that the photos you took of private company documents by social engineering your way inside must clearly be unsecured and publicly distributable because "they were given to me when I asked for them".
This isn't slipping through various open doors. There were no doors. This is literally a public server on the public internet serving files publicly. Intel is grossly negligent in securing their assets if they're hosting what they consider to be confidential trade secrets on public CDN servers.
The analog would be if I posted a flyer on a telephone pole with what I considered confidential information and someone else took a picture of it. There's no way you could argue that I had a reasonable expectation that only people for whom the flyer was intended would be able to view the flyer.
If someone deliberately bypassed computer security measures to acquire this information I'd agree. But you don't get a free pass to be negligent just because you're a big company. I suspect the EFF would support my viewpoint as they supported Weeve's appeal of a much more contentions and ethically gray scenario (the acquisition of personal information from a server that was negligently "secured" and required someone to imitate the calls an iPad would make).
Then search engines must not be legal. They crawl the public internet and index what they find.
What you’re effectively saying is that the flyer is unknowable unless a Street-view car drove past and snapped a picture of it and its owner engaged in SEO to make sure it landed near the top of search results.
There is no “house” in this analogy (which you might call a corporate/private network secured or otherwise). No private network was accessed. This stuff was on the street, in the free pamphlet section of the newspaper stand.
