Harald Welte writes 'The netfilter/iptables project has just been granted a preliminary injunction against a GPL infringing WLAN AP Vendor. The project is trying to fight against the increasing number of products sold in violation of the GPL. Following a number of out-of-court settlements, this is the first case where a company refused to sign a letter to cease and desist. So we took the logical next step and applied for a preliminary injunction. The court reviewed the case and confirmed that Sitecom is in fact in violation of the GPL license terms.' [...]"
A very interesting case, indeed. We shall wait and see if this decision will be upheld by the Munich district court during the main court proceedings.
