Mybe its only my reading of the article but the inference I was making was that whilst Datalink had been found guilty of using trade secrets in Canada - it hadn't in the US. Meaning that it is still free to help sell its products in the US, hence having distributors - that seeing a crafty buck - set up websites that can cover both US and Canada.
I have to wonder here if the root cause is failure of the aggrieved party to go after Datalink in the US via copyright, patents or what ever other due process exists and therefore instead getting the Canuck judge to extend the reach of his judgment into the US - albeit only for those results accessible by a Canuck domain (.ca).
The fact that the distributors are playing whack-a-mole with google over the domain names - suggests to me they may be a little bit shady. i.e. the only reason to try to get around the block is if they know of and are deliberately trying to flout the judges order.
Having said that - with their vaunted search prowess Google should excel at whack-a-mole of this type.
