The restriction in the EULA seems overly broad to me. First, it seems unenforceable (but I'm not a lawyer). Imaging a publisher who says "you may read this book but you may not publish a review of it without approval from us first" or GM saying "you may drive this car but you may not divulge your MPG or cruising speed" etc. Second, it seems highly undesirable for VMWare to enforce it. Would they want to bring more publicity to bad performance results by suing the whistleblower? who is only a customer, not an employee? Of course anyone would sue in the case of libel by fabricating or otherwise mistating poor results.
I have nothing against VMWare but I dislike unenforceable, overly-broad restriction clauses.
