Since you quoted me, and presumably your response was directed to me, I will, in turn respond.
How you treat warranty is your choice, and I do not presume to judge you for it - in fact, personally, I share your approach.
I was merely commenting on the question asked by the previous poster, and, being responsible, advising him fully, so that he was in a position to make the same choice as you did - whether or not he wishes to use the firmware, and in so doing, possibly voiding his warranty.
