The VMware End User License Agreement reads as follows:

2.4 Benchmarking. You may use the Software to conduct internal performance testing and benchmarking studies. You may only publish or otherwise distribute the results of such studies to third parties as follows: (a) if with respect to VMware’s Workstation or Fusion products, only if You provide a copy of Your study to [email protected] prior to distribution; (b) if with respect to any other Software, only if VMware has reviewed and approved of the methodology, assumptions and other parameters of the study (please contact VMware at [email protected] to request such review and approval) prior to such publication and distribution.

My questions are:

  • What happens, if you refuse to take your unapproved benchmark down? Can they sue you?
  • How much leg does a clause like this stand on the courts? In the United States? In the rest of the world?

IANAL, but a EULA is a Contract of Adhesion https://www.law.cornell.edu/wex/adhesion_contract_contract_of_adhesion and restrictions against publishing benchmarking data about products is fairly common https://www.eff.org/wp/dangerous-terms-users-guide-eulas

A contract is a contract, even a click-through, and is legally binding; there is plenty supporting case law. You sign when you click: http://smallbusiness.findlaw.com/business-operations/contracts-and-electronic-signatures.html

Basically, VMware has lots more money than you do. If they are annoyed at your posting of benchmarks that don't make their products look as good as they feel they should, they can at very least send a DMCA to the site that posts the benchmarks. Whether that works could depend on where the website is hosted. At most, they could take you to civil court, if you are in their jurisdiction.

What happens, if you refuse to take your unapproved benchmark down? Can they sue you?

Yes. (In civil, not criminal court).

How much leg does a clause like this stand on the courts? In the United States?

A contract is a contract. And VMware and you (I assume) are in the US, so the contract is enforceable.

In the rest of the world?

Outside of the US, enforceability is variable; that is searchable in law databases for each country and agreements between countries.

Consider your motives for posting benchmarks against VMware's EULA. Do you have good points to make? Or are you simply complaining about the product? Who has more money to spend defending or fighting the EULA? You or them?

If you're seriously concerned about this, talk to a lawyer and don't take legal advice from the general public.

    Even before suing, the company could rescind your software license and/or restrict you from purchasing a new license.

  • True, they can cancel the license, and that's outlined in the EULA. But, in the real world, that can mean little; the PC/Mac client version of VMware will still run, though VMware could restrict updates; a server version of VMware could possibly be deactivated by VMware, if there is a backdoor to do that, and if they outline that possible action in a EULA. The EULA linked in the question appears to be for a download client version. Feb 19, 2016 at 19:27
  • @BlueDogRanch -- the fact that software runs does not mean you have a legal license to the software.

  • @soren: I'm not contesting that fact; I'm simply saying it's reality. Feb 26, 2016 at 15:46
  • No, I'm not in the US.
