The microsoft story is talking about the very chip in the picture. So there's nothing wrong or illegal about that. Similarly, two of others are stories about the ARM processor, so showing a picture of it it perfectly legal, and I assume authorized by the the chip manufacturer.
The fourth is a minor copyright violation (not trademark, because they are not representing it as a different product) by a university on its electrical engineering degree page. It's quite conceivable that they paid a small fee to use that picture, or just used it without permission knowing the worst case scenario is a cease and desist letter. By all means, send "Rebecca" all your bitcoins.
And guys, the "Number Left In Stock" thing on their website is fake too. They are surely making it go down to look like they are selling their imaginary machines. Trust me, they will always have some "in stock" for any sucker willing to pay up.
