"Unsafe despite software patch" - the modern day Corvair. I'll never fly on one of these, and neither should you. Boeing needs to get their act together...
GM's choice to recommend lower inflation pressures for the tires vs installing an anti-sway bar for the first gen cars with swing axle rear suspension (2nd gen was IRS) was rather stupid but it's nothing compared to the 737 MAX.
Will that happen? No, thus a new(ish) and now chronic distrust of the company and the decision that it makes.
Once you have a bad culture established in an organization it's very hard to turn that around absent a rather drastic purging of employees at multiple levels combined with a very pro-active new management that not only talks about the necessary new culture but also actively implements the incentives required to enforce such a culture.
Personally I've had to deal with cultural turn around efforts at companies in the past (albeit nowhere near the scale of Boeing) and over time I learned that the only reliable way to address such a situation is to purge with fire and bring in new people.
You're thinking of the de Havilland Comet (or possibly the aircraft manufacturer Convair).
And, can you document it rather than just claim it?
