Calculating correct resistor value to protect Arduino

Why all blink tutorials use 330 ohm resistor. Ask Question 3. When I do the led calculation I found 150 ohm resistor is enough for 3mm red led. If so why all arduino tutorials, like this one, are suggesting 330 ohm resistor? I assume V = 5 Volt, diode forward voltage = 2V and diode forward current 20mA.

LESSON 13: Controlling RGB LED with Arduino - Technology

When building your Arduino projects, you use resistors to limit the amount of current going to certain components in the circuit, such as LEDs and integrated circuits. Here is an example for powering an LED: (5V a resistor with brown, black, brown, and gold bands is a 100Ω resistor with a 5% tolerance. In addition, the Circuit
