The counter argument is that the more people learn a strategy to do "a thing", the more likely that they will implement that strategy incorrectly. I use texas holdem as my example, in the poker community people are constantly complaining about the high level education services that players can opt into. But the reality is these services actually pump up the poker economy and churn out players who misapply the concepts. Trading is exactly the same, its good for the economy to educate new traders to help keep them in action - but the majority of these newly educated traders will misapply the concepts regardless.

TLDR: Nothing to worry about, information wants to be free!
