Your response explains SO much about why this is a dumpster fire. Rather than a professional "these are some valid concerns, we may have made some serious mistakes and this deserves a credible response", here's how your defensive commentary was received by at least one person:
"Public criticism (however valid) of something I worked on hurts my feelings. Just so you know, we already thought through ALL these possible "problems" (and more) and we chose the "one true way". So your criticisms are just, waves hands, whatever.
Plus, these "issues" could never happen anyway (just try it lol!), so your criticisms are basically imaginary. Also and anyway this is YOUR fault (not mine, no!) because YOU wanted extensions. Also, also: the other guys were worse. Your fault, shame on you, other guys worse, I'm a good person.
And finally, this is hard work, no-one ever said thank you to me."
