If this was the case, one the one hand they should be criticized for releasing such bad laptops on the market but if they had already decided on developing their own silicon then maybe it made sense to just accept that some generations of Macbook were going to have thermal issues and focus all efforts on the future.
They placed a large bet for the MacBook on Intel’s roadmap at exactly the wrong time, and it screwed up multiple product planning and execution generations as a result.
Apple has finely tuned their organization to be great at long-term plans. That has come at the cost of being able to adjust “quickly” when those plans end up being flawed. The fiasco with the butterfly keyboard is maybe the best example.
