Stealing an idea, can the post still be original content ?!

Let's say you make a post with this tittle: ' If this post gets over $2000 I will eat a sock' and in 6 hours you make $0.03. It's not important how much you make just to be clear; someone else copies your post, and he makes a small change. Something like this:'If this ugly post gets $ 2,000 I'll eat a sock + video #steemitchallenge'. He makes $154 in 34 minutes only because he changed the tittle? What can I say? He's tittle is different and he will make a video, only IF he will make $2000 on this post. Here is a big IF ok,

and let's say he will make $2000 and maybe will make the video too. I don't know if he will eat that sock, but everyone wants to see him do it, right? I'm not interested to see him eating that sock, I want to know why people are saying that He only stole the idea.

Let's say that I agree with that, but I don't; what makes the second post(the stolen one) different from the original one.? Where is the original content in the stolen one? I don't see anything original there, but people see it. Where? I'm eager to see if someone will answer this question.

Is this the way to help the STEEMIT community, by copy paste? Let's all do it then, if this is the answer, we want to help too!!!

Think about this: you post something amazing, but maybe you miss something, and maybe it takes you 2-3 hours to figure it out, meanwhile someone copies your post changes something, and VOILA: JACKPOT! What then? Will you still say that he only copied the idea?
