Exactly and quite frankly unsurprising.
There is a complete delusion and a myth going around on HN that ‘seniors’ are not affected by these layoffs and proponents of that could not have been more wrong.
It is perfectly reasonable to fire them as they are totally expensive and a giant cost center to the business and to keep some extra cash would be to just reduce or remove the deadwood. Some juniors can be kept and paid less but most of them can also be let go as well if they are not quick to learn.
It was unsustainable anyway. A well deserved reset of the tech bubble that finally corrected and burst.
