[Issue] Modifications to the contract [Comments] 
Vendor form contracts sometimes reserve the right for the vendor to make modifications to its services unilaterally. While some form of right to make changes probably is necessary and appropriate – we certainly would have no objection to improvements – such language is overbroad and does not provide the customer with any assurance that any such modifications will be beneficial, let alone acceptable. Limiting the vendor’s right to "commercially reasonable modifications" would be an improvement, but, in the context of a "free" service, could still be expansive. Even better would be to add to that a qualification prohibiting "materially detrimental" modifications – perhaps something to the effect of "Vendor may make commercially reasonable modifications to the Service, provided that they do not materially diminish the nature, scope, or quality of the Service."
