So a lot of this increase in bug reports lately is simply that we are more able to find issues which would previously have been shipped and probably wouldn’t have even been noticed by users for a long time. The minimum bar for software quality is going up, there's no excuse to ship software which contains bugs that could be detected by an LLM.

Unlikely, from the context.
> Might someone have offloaded their thinking to some external tool?
No, according to the author, since the features predate most current LLM assisted coding.
> Did people stop caring?
I'm not sure what this means. Presumably things were reverted because people cared enough to make sure it was good quality before being released.
> Did someone not plan or design a feature in full?
An admitted possibility

Depending on what you mean, that may be correct according to the article, but I suspect not in the way you mean.
> Maybe with so many reverts timelines should be revised?
It sounds like there was a very large increase in load in some of the people that would commonly review during this time period, and that may or may not continue to happen to a greater or lesser degree in the future, it depends on how LLMs advance in finding bugs and if there are other large waved of bugs reported.
