If this is true that that's inexclusable and shitty. Still legal(?), but not ethical. Looks like the they're being challenged in the court.
Whether firing was done ethically or not, I still think that Twitter was bloated af and needed trimming. The macroeconomic conditions led to a huge hiring spree for last 8 years of 0% interest rates. We fucked around in the silicon valley and we are about to find out.
Overall, on a national/GDP scale, we can use these employees for betterment of other things than wasting their time at FAANG/Twitter. I'd like to see 1000 lean and mean companies than 10 bloated FAANGs.
