Ask HN: I have received a Cease And Desist letter. What to do?
11 by robbiejs | 11 comments on Hacker News.
Hi, I am Robbert, creator of JavaScript Excel-like data table library DataGridXL ( https://datagridxl.com ). I made this component since similar products are quite slow & unreliable. I just released version 2 of the product and decided to add a few "Comparison Pages" to my website, to show visitors why my product is better (when it comes to performance & reliability). Now, the most well known JavaScript Excel-like data table libary has sent me a Cease And Desist Letter by email (twice) demanding that I take this Compare page ( https://ift.tt/aKk1mwl ) offline. I am not much of a legal rights expert, but so far I have ignored it. I can publish whatever I want, right? Freedom of speech? So far I have just laughed it off and considered it very childish for a 20 person company to try to pressure me into taking this page offline. However, I could use the advice of the Hacker News community. What should I do here? Ignore or take action?
