Andrej did answer, he said that the delta was tested and found wanting, then detailed a number of risks that came with keeping Lidar. Positive but small. Risks larger. That exactly answers "don't you want all the help you can get." (paraphrase, from memory.)
Securing supply chains is hard period. Tesla and SpaceX have gone to heavy vertical integration because ensuring quality seemed to insist upon that.
What specifically would the new management team do that would secure supply chains trivially, etc? What's not being done?
Change management has nothing to do with people management.
It’s about managing changes to your product. It’s extremely important part of any safety critical system. And something that most new companies ignore, as it’s costly.
And maintenance etc. But if you don't gain significant benefit, it's reasonable not to take on the risks of managing changes to a product you can do without because it doesn't, itself, significantly reduce risk.
