Before you accept Legal's softening of your promise, try a different level on the "weasel word continuum"
You've submitted copy to Legal (AKA, the Sales Prevention Department) and they say your promise is too strong. Before accepting their way of weakening it, propose other options along "the weasel word continuum." You may be able to dial your promise back without dropping it all the way to zero.
Here is my take on the continuum, with "Does / will / is" being a neutral statement of fact. Each modifier above it represents a strengthening of your promise. Each qualifier below it represents a successive tempering of your promise.

When two positives make a negative
The professor was lecturing his class.
"While two negatives make a positive," he said, "two positives can never make a negative."
A voice came from the back, "Yeah, right."
