"Don't count your chickens until the eggs hatch".
Not a hard principal to follow, and yet no one did. Not TPL, nor Moore, or PTSC. They all acted stupidly and fell right into the infringers hands. They just waited for all these idiots to spend the money they made and then cut-off the revenue and try to starve them out. Not smart business tactics and certainly not deserving many chances to just act stupid again.
