I hadn't heard about this before today and doing a bit of research it sounds like something that has been going on for years - since at least 2007 - and there has been some really dodgy practice. (But I still don't see why Google is targeted here).
And it seems that Datalink have made some effort to clarify the situation: http://1770-kf3.com/
> We would like to clarify that DataLink no longer sell/promote the following Canadian manufacturer’s products. “Equustek Solutions Inc.’s products (www.equustek.com), as listed below, are no longer distributed by Datalink:”
“Customers of these products should contact Equustek directly at the website above or toll free at 1-888-387-3787"
I don't know this area so I have no idea what I need to type into a search box to get a Datalink result turning up where I should be getting an Equustek result. (And I'm trying across different search engines).
