Neither Conservancy nor Christoph takes this action lightly nor without exhausting every other possible alternative first. This lawsuit is the outgrowth of years of effort to convince VMware to comply with GPL.
In October 2011, Conservancy received a GPL violation report on BusyBox for VMware's ESXi products. Conservancy opened the matter in its usual, friendly, and non-confrontational way. Nevertheless, VMware immediately referred Conservancy to VMware's outside legal counsel in the USA, and Conservancy negotiated with VMware's legal counsel throughout late 2011, 2012 and 2013. We exchanged and reviewed CCS candidates, and admittedly, VMware made substantial and good efforts toward compliance on BusyBox. However, VMware still refused to fix a few minor and one major compliance problem that we discovered during the process. Namely, there was a major violation regarding Linux itself that ultimately became Christoph's key complaint in this lawsuit.
Meanwhile, when Conservancy realized in late 2012 there might be a major Linux violation still present in VMware's ESXi products, Conservancy representatives sought every industry contact we had for assistance, including those from trade associations, companies (both competitors and collaborators with VMware), and everyone else we could think of who might be able to help us proceed with friendly negotiations that would achieve compliance. While we cannot name publicly the people we asked for help to convince VMware to comply, they include some of the most notable executives, diplomats, and engineering managers in the Linux community. No one was able to assist Conservancy in convincing VMware to comply with the GPL. Then, in early 2014, VMware's outside legal counsel in the USA finally took a clear and hard line with Conservancy stating that they would not comply with the GPL on Linux and argued (in our view, incorrectly) that they were already in compliance.
Conservancy in parallel informed Christoph fully of the details of the Linux violation on Christoph's copyrights, and based on Conservancy's findings, Christoph began his own investigation and confirmed Conservancy's compliance conclusions. Christoph then began his own enforcement effort with legal representation from Till Jaeger. Christoph has been unable to achieve compliance, either, through his negotiations in 2014. VMware's last offer was a proposal for a settlement agreement that VMware would only provide if Christoph signed an NDA, and Christoph chose (quite reasonably) not to sign an NDA merely to look at settlement offer.
Thus, this lawsuit comes after years of negotiations by Conservancy to achieve compliance — negotiations that ended in an outright refusal by VMware's lawyers to comply. Those events were then followed by a year of work by Christoph and Till to achieve compliance in a separate action.
Simply put, Conservancy and Christoph fully exhausted every possible non-litigation strategy and tactic to convince VMware to do the right thing before filing this litigation.
