That's the problem, though, isn't it?

Someone could see a $500/pm idea in this thread, being developed by a solo dev, and think: "that's a good idea". They put a team of seasoned devs on it and created their own $500k/pm version.

If that is the case, that idea was in the wrong hands to begin with. All the successful ventures you see seeded by an idea but grow to the success that they are because of execution and good ol' fashioned luck. There is nothing original or groundbreaking in Slack for example. Nor are they the only ones playing in that space. But Slack are Slack because they executed well enough and luck was on their side (right place right time).
