I find the explanation posted in the question more fascinating than the actual answer:
while in High School, Dorsey's father used to spur him to work harder with that exact sentence.
For me, this implies that the creator of Twitter hated his father's trademark phrase, and by extension his father's demands to work harder, so much that Dorsey would explicitly put a ban on the phrase to spite his father.
This follows humanity's tradition of creating myths to explain things we don't understand[0], but it's exciting to see the mystery phenomena revealed as something created entirely by man.
