This email is basically:
Oh dear we're in a tight spot, no idea how we got here, it's a mystery! I guess someone (definitely not me!) ran the business in a way that demonstrated an appalling understanding of our market, our customers, and the macro climate, and a fundamental carelessness with investor money and employee livelihoods. Don't worry though, that person was definitely not me, so I'm the right person to lead us out of this.
p.s. look shiny severance packages!!!
p.p.s. Once again, that person was not me, so there shouldn't be any consequences for me, other than a bunch of easily impressed tech workers giving me praise for the severance package.
