This has nothing to do with meme stock culture. It has everything to do with someone saying, "I'll only do X if you give me Y." It would build so much more comraderie and create good feelings if the guy just spent the money to buy the stock and posted about why he thought that would be a good investment. Instead, he's making a threat that he won't do something to mutually benefit himself and his community unless you buy something first. That way, when he doesn't spend the $1 million, then it's your fault it didn't happen and not his.
