That's not as surprising as you may think. "Truth is not a complete defense against libel".
Imagine I contacted someones workplace and business partners and told them about a drug conviction that occurred 22 years ago. Or if I took a statement you make after a some drinks in the pub and stuck a print out on poles all around your business.
There are cases where suing someone for libel even if what they say is true doesn't seem demonstrably wrong.
I thought this short video was pretty insightful. I have been focusing on pitching the benefits of my product and not reducing the risk of adoption.
By talking about all the different way my product can help perhaps I was making it look like it would be a dramatic change to the customers workflow.
I am going to focus on the single most significant benefit we offer and suggest a "one week challenge", where the customer uses our product for a week and then we discuss the benefits.
