I'd be real curious to see their ROI calculations on this strategic move. Laying off those 1800 employees will cost them $260 million, before factoring in hiring costs for 1800 highly technical replacements.
Salaries for experienced SWEs in Boise are cheap. Looking at levels.fyi there's a recent salary from an Android engineer with 5 years of experience grossing 143k. If they're looking for FAANG talent they won't even be able to poach a college grad for that amount.
