This comes back to what I suggested here Filter forwarded packets if on limited cellular plan - #19 by Jeff-UK it may be the user is oblivious to either status of their nodes or the TTN network needs so I would approach them to inform & educate… 
if a commercial node with no firmware access & operating in edge of reception as indicated then to improve then their solution may have to be adding extra gw(s)… which would be a result for the local community
