Nagios-Plugins Web Site Taken Over By Nagios
Found on Slashdot on Sunday, 19 January 2014

Holger Weiß, formerly of nagios-plugins.org, announced that 'Yesterday, the DNS records [of nagios-plugins.org] were modified to point to web space controlled by Nagios Enterprises instead. This change was done without prior notice. To make things worse, large parts of our web site were copied and are now served (with slight modifications) by Nagios. Again, this was done without contacting us, and without our permission.
Seems like it was a good idea to use Icinga right from the start instead of Nagios. Yes, Icinga makes use of the Nagios plugins, but still.
