I just looked at 1024 on Google Play, and I have to say it would really sting to work on Threes for a year then read that "If you played 2048 in Hacker News, That [sic] you should know this is the original one."
Have you seen the original description for 1024 on the app store? I see they've updated it to be less tasteless, but luckily the internet never forgets:
"No need to pay for ThreesGames. This is a simple and fun gift for you, and it’s free."
