It is ignored because something else came up and that one was forgotten.
They might not even be able to differentiate from risks and deliverables. Tasks falling off any list shows that the relative importance of the task is not known, only recency is.
There isn’t a culture of trust, where people are encouraged to bring up problems and can instead be labeled as slowing a project down. There is also a culture of deliberately avoiding acknowledging issues in hopes they will just go away. This leads to a lack of decisiveness because nobody wants to stick their neck out to either say “no we don’t think that’s a credible risk” but also don’t want to invest resources in mitigating that risk.

If I were Ebeling, I'd've punched my manager.
* yes, they knew of the foam shedding, and knew it was out of spec. But they didn’t realize it could puncture the tiles in that manner.
They saw hundreds of spots of damage and decided it was just a nuisance, they never considered that there could be spots that wouldn't just be a nuisance. Beancounters unwilling to acknowledge a problem until it was decisively proven--and the only proof was a loss of the orbiter.
It wasn’t really a “beancounter” issue. It came from the fact that we have imperfect models of physical systems and sometimes we encounter issues outside the boundaries of those model assumptions.
The story as it is often told is that an engineer raised issue X, management dismissed it, issue X caused multiple deaths.
And when told like that it is obvious that management should not have ignored X. But what were the managements’ experience with warnings like that before?
Obviously they should have evaluated every warning on their merrits, but if the organisation was “crying wolf” all the time, one can imagine that can influence the decision making.
Still, to try and give you some examples, Google Glass was known to be a failed product early on due to technical and practical problems voiced by engineers. But there was a culture of optimism or wilful ignorance at Google about Glass, so the project continued until it died due to these problems. And there are some articles on Hacker News about it. Right now there are murmurs online that Meta engineers are very aware that the metaverse is not engaging and VR efforts should pivot elsewhere. Yet the management seems to ignore this, even at tremendous cost to the company value. The whole VR effort at Meta could die because of this.
The interesting aspect of this culture is that it's not a "hindsight is 20-20" situation. In complete contrast, it's that engineers bring up problems that will significantly harm a project or a company in the future, but are ignored.
Also, Google Watch is basically Google Glass on a wrist, so building it out wasn't a complete waste.

I think that you hit the nail on the head with the word "trust" - in many companies there should be more trust from management that engineers understand the context within which they work, and could have very unique and valid insights into how their software and hardware will be received by the consumer.
