Looking for UI/UX help
So, I recently discovered that my indie extension has been cloned. To add insult to injury, actual code I've written is present in the stolen clone -- sure, lightly "edited" -- the names and such, but its clearly a paste.
Now, the extensions all live on webstores of the browser we submitted to. What are usual recourses here? Are there any? What are community thoughts on the topic? Is this fair game for any low hanging fruit?
