Lying to people and manipulating their sympathy to validate a business idea is wrong. I imagine the OP didn't imagine this was something that had to be pointed out to people--even if you don't agree with that viewpoint it's not exactly a difficult one to imagine, and it's better to state as a premise that it's a bad idea rather than bog down a blog post--which seemed more focused on discussing alternative methods--into a tedious moral argument that won't convince anyone.
I dont think saying my idea as my friends idea is much lying. But I do think that you should be straight about it being your idea and use conversation skills to make sure people still give you honest advice.
You lie to people every day just to function normally in society. You must be a terrible sinner. Boo hoo.
While were at it let's throw in a good dose of violence, because that can help us get what we want as well.
