There is a place for education, and there is a place to simply answer the question posed. Yes, we impart education, but one could answer the question and THEN add the 'there is a better way, however...' as follow on commentary.
And it is good for someone to master the simple stuff and progress up to the sophisticated stuff, learning at each milestone in their progress. Besides, many hobbists simply lack the space for softboxes to be used, whereas umbrellas occupy less space.
Am I doing you good, if you drive a Toyota Corolla, and I tell you how wonderfully you can escape accidents with the power and the clutchless manual transmission of the $50k car? Yes I am making you aware, but I am also not helping you to use your Corolla to best advantage.
