there's a special place in hell for billionaires laying people off with one week severance before Christmas.
Again, not excusing any of this, the video was extremely cringe and I can't believe he went with "for those of you in the US, we'll be doing the legal minimum, for everyone else, sorry!", but as someone who is "worth" almost a million dollars, and who cannot afford to hire even a single person, it's not always so simple.
All that said, 900 * (150000 / 12) == 11250000, so I have a hard time imagining it wouldn't have been worth 1M for a fairly well known tech company with loads of funding to avoid this horrific press and karma.
