Should they be stopped because they don't use "Linked Data".  Of course not.  Nor should they be asked to use a different term.

I don't understand your juxtaposition  of "Linked Data principles" and 
"Linked Data".  If they've embraced "Linked Data principles" how do then 
end up not being "Linked Data" compliant?

Why?

Linked Open Data is about Linked Data principles applied to the 
enhancement of publicly available data that already exists in some 
standardized structured form.  For example, DBpedia is about applying 
Linked Data principles to Wikipedia content. The entire LOD cloud is a 
collection of data publications that adhere to the principles outlined 
in TimBL's original Linked Data meme.

Open Data is basically about structured data *modulo* mandatory 
exploitation of hyperlinks en route to enhancing data representation 
fidelity.

We are conflating Open Data (one form of structured data) and Linked 
Data (another form of structured data).

All Linked Data isn't necessarily publicly available. All Linked Open 
Data is publicly available.

All Linked Data is Structured Data. All Structured Data isn't Linked 
Data. These distinctions really matter.

But we have names for a reason :-)
