Literally millions of animals die every day as a byproduct of animal processing industries. As in, death in a way that doesn't result in any sort of useful consumption.
True, but it's a cost of doing the business. In general, if there was a way where we could do that processing with less animal suffering we would. In Neuralinks case they could have done their business with less animal suffering, and chose not to.
They are not by far the least worst offender. Medtronic, J&J, all the big med tech and pharma companies do this work day in out, for decades, and none of them do it this way. Neuralink is by the far the worst, and that is why there are articles and former employees saying so.
