This is all voluntary work. It is not difficult to see your side. You do not have time. You can drop or ask more time. You  prefer to drop it. What is disappointing is not your decision, but solving the problem with users who WP:OWN and do not negotiate on the WP:Verifiability. You do not need to take it personally, it is not directed at you, but to whole system. This point is clearly stated at the link, which was your advice to apply. I also do remember clearly thanking for your efforts. I'm sincere in my efforts, also my disappointment. Thank you. one more time.
