I think a special mention should go to hardware vendors who adopt this 
dreadful practice in network equipment. I recently encountered an 
enterprise-grade WLAN router from vendor D that has the horrible habit 
of intercepting some % of queries to its local DNS cache resolver and 
forwarding to an affiliate Yahoo! search page, lousy with ads, under 
vendor D's control.

This includes things like www.google.co.uk. I don't manage this device 
and therefore have opened a ticket with those who do to get them to turn 
the damn thing off, while in the meantime adding *.[vendor D]search.com to my /etc/hosts.

I must admit to being tempted to "fault" it with something heavy in 
order to force its replacement:-)

But if anyone from vendor-D is on the list: congratulations, you've 
managed to invent a network device that is by definition untrustworthy, 
and I will never buy anything from your company.

The only thing worse than e-mail disclaimers...is people who send e-mail 
to lists complaining about them
