I think that Raspberry Pi Foundation is correct here. I think that this is just a notice to not use Raspberry Pi in the site and transfer the domain to Raspberry Pi foundation (this is questionable).

Reason why i am saying this is that i saw this article with the title

"Introducing the Raspberry Pi 3 B+ Single Board Computer"

https://www.raspberrypi-spy.co.uk/2018/03/introducing-raspbe...

They could have written "Review of" instead of "Introducing" .

At the end, I think that Raspberry Pi must also clarify properly the terms of usage of their assets in their website. For media usage,it is better to permit users to use some assets.
