No, they literally failed or never took Intro To Engineering Safety / Ethics.
It is flat out irresponsible to sell a board with a fine line between normal operation and critical failure with an anemic, easy to miss warning system, that straight up cannot kick in in some failure situations or will exacerbate the problem.
They were irresponsible morons for not including an audible alarm initially, and they were wreckless and greedy assholes for having the capability of haptic feedback but never enabling it.
As someone who has to read multiple engineering safety textbooks, this is literal textbook bad engineering and there’s a reason the CPSC isn’t going after EUC makers who included alarms on every single model.
