What I think they mean by this is that you shouldn't link to resources on their website to make it seem like they endorse your (product, website, whatever).
From the legal disclaimer at the bottom:
> linking to this website without written permission is prohibited
"If you have any comments about our WEB page, you can write us at the address shown above. However, due to the limited number of personnel in our corporate office, we are unable to provide a direct response."
I see they have a link to "Berkshire Activewear". Now that's a much much more heavyweight page.
Can it be assumed that this same website has been in place since 1978? Obviously not exactly like it is now, but probably not far off.
But, the website looks rather similar to how it did back in 2001 (with the recognizable two-column list of bullet points):
https://web.archive.org/web/20011129002047/https://www.berks...
I wonder what the logic for the 1978 date is. It's hard for me to believe they had any reasonably connected predecessor of this in 1978.
How about you average their subsidiary web pages? Start with DQ.com (Dairy Queen)
