Implode-o-Meter News - Delayed, not saved: Foxconn's Wisconsin

The factory is not back on. LCDs are pure commodities, among the lowest-margin components, and about to be made obsolete by OLEDs. There is zero business-case for building these outside of Asia-Pacific. It was a stunt, it was always a stunt, just like it was a stunt all the other times they did it.
The reason for the announcement is that Donald Trump called them up and asked them to announce that the factory would be built. Donald Trump will be president for two or fewer years, during which time Foxconn can dither and dick around and do very little, and then they can announce that the factory is off. This news will be welcomed by Trump's successor, from either party, as a way to further discredit him.
