At this point, it feels like chipmakers are just eager to find yet another excuse to slow down production.

This plant closure appears to have been in the works for several years so it is unfathomable that the chipmakers are not prepared for this.

I would not underestimate the power of denial mixed with a healthy dose of arrogance and stupidity.

Based on what I've seen in the corporate world, I think it's far more likely that chip makers convinced themselves that, given how critical this plant is to the chip supply chain, either 3M would finally address the issue or the Belgium government would blink, and so continued to operate as usual.

Frankly, I expect 3M thought the same, hence their half-assed and illegal attempt to fix the issue.
