Of course you can copy the product as such, that&#x27;s fine by me and I think even necessary.<p>They&#x27;ve gone far beyond that here though, copying not just the product but significant parts of the design. The Quitter thing looks almost exactly like Twitter. If they&#x27;d copied the website of a bank like this, it would be considered phishing.<p>This is well beyond copying an idea or a few design concepts.
