I presume you are familiar with this:

When I contacted D-Link back in November 2005 about the way D-Link 
products abused my NTP-server, I expected to get in touch with somebody 
who understood what they were talking about, I expected them to admit 
that D-Link had made a bad decision and I expected that D-Link would 
make good on the damage they were responsible for.

For the last five months I have wasted a lot of time trying to reach 
some kind of agreement with the Californian lawyer which D-Link put on 
the case. I can’t quite make up my mind if D-Link’s lawyer negotiates in 
bad faith or is merely uninformed, I tend to suspect the latter, but 
either way, as of this morning I decided to cut my losses.

Since no one else at D-Link has reacted to my numerous emails, I have no 
other means of getting in touch with D-Link other than an open letter. I 
realize that it will be inconvenient and embarrasing for D-Link to have 
this matter exposed in public this way, but I seem to have no other choice.

I will now lay out the case below in such detail that any moderately 
knowledgeable person should be able to understand it, and hopefully 
somebody, somewhere in D-Link will contact me so we can get this matter

    "D-Link and Poul-Henning Kamp announced today that they have amicably
    resolved their dispute regarding access to Mr. Kamp's GPS.Dix.dk
    NTP Time Server site. D-Link's existing products will have
    authorized access to Mr. Kamp's server, but all new D-Link
    products will not use the GPS.Dix.dk NTP time server. D-Link is
    dedicated to remaining a good corporate and network citizen."
