I actually got the finger as a present back in 1982. I blame the complete lack of Dark Crystal toys on the market for this. At least it was more screen accurate than some of the other E.T. toys back then. The official plush toys were hideous.
And apparently somebody thought it would be a good idea to revisit this with the whole hand!

P.S. If anybody wants to get me something really nice for my birthday, this is in the current Prop Store auction. ;)
Unless there's some other cute character in TFA we haven't seen yet. I'm betting an electronic BB-8 is what kids will be clamoring for this Christmas.
