Thanks, it's interesting you see it that way - but I've never seen that view common among 'hackers'.

So, I doubt that's the factor why the symbol hasn't been more widely-used, emblematically. I instead suspect mixed-feelings about anything ESR proposes, or just more generally the fact that hackers are so varied in interests/behavior that there's little need for a shared emblem. (Though, the glider appeals to a certain mindset, who have & will use it as a symbol, as when it appeared in many remembrances after John Conway's passing.)
